Chapter 1 SMAPI Overview

This chapter describes the format of the function calls that are presented in Chapter 3 “Function Calls
to the Speech Recognition Engine” and Chapter 4 “Data Access Functions”. Chapter 3 contains the
function calls that go directly to the speech recognition engine. Chapter 4 contains the function calls
that do not interact with the engine; they provide local access to the logical contents of a message that
has already been received.

This chapter also lists the calls by functional group.

Format of the Function Call Descriptions

The description of each function call contains the following information:

Function Name

The name of the function call.

Purpose

The purpose and description of the function call.

Syntax

The syntax of the function as declared in SMAPI.H.

Parameters

Definitions of the parameters.

IBM SMAPI Reference

SMAPI Overview

Return Values

Return values are listed in two groups:

.
Return values that are set by the SMAPI or as a result of an unsuccessful connection to the
speech recognition engine. These values are always returned by the called function whether it
was called synchronously or asynchronously.
.
Return values that are set from within the speech recognition engine. These values are returned
by the called function only if it was called synchronously. If it was called asynchronously, the
speech-aware application must retrieve this type of return value from within the appropriate
callback by using the SmGetRc function.
For detailed descriptions of SMAPI errors, reference “SMAPI Return Codes and Messages” on
page 369.

Reply Structure Functions by Message Type

A list of all reply message structures that can be received from the speech recognition engine; and
for each listed reply message structure, the SmGet functions that can extract data from it.

Task Related Functions and Callbacks

A list of functions and callbacks broadly related by task to this function. This is applicable to
functions that do not return a reply structure. For example, task related groups include:

.
Vocabulary Processing
.
User Processing
.
Application Initiation
.
Speech Processing
.
Application Termination
IBM ViaVoice SDK for Windows

This section also lists related unsolicited callbacks.

Reply Structure-Related Functions and Callbacks

Clarifies when the SmGet functions can be called. If the function prototype SmXxx is listed as
related for any SmGet function, then that function can be called as follows:

.
Immediately after a synchronous SmXxx call
.
From SmNXxxCallback after an asynchronous SmXxx call
.
From the message reply structure after an asynchronous SmXxx call.
Naming Conventions

Use the following conventions when creating various IDs and names passed to the speech recognition
engine:

.
User IDs can consist of only lowercase alphanumeric characters plus the underscore and
hyphen characters.
.
Descriptions cannot contain a new line character.
.
An ID must contain at least one character.
The following values, found in the file SMLIMITS.H, shows the maximum lengths of key variables:
#define SM_MAX_USERID_LEN 8
#define SM_MAX_ENROLLID_LEN 8
#define SM_MAX_TASKNAME_LEN 8
#define SM_MAX_SCRIPTNAME_LEN 8

Parallel Session API Calls

The feature of having multiple engine connections from a single application is known as parallel
sessions. If you want more than one connection from your application, you must use the parallel
session calls. The name of a parallel session call is the same as the regular function call except for two
things: the name of the call has the characters Ses inserted after the Sm, for example the parallel
session disconnect call is SmSesDisconnect. Secondly, each parallel session call takes one additional
parameter, which is the session ID. This is always the first parameter. So for the disconnect example,
the call is SmSesDisconnect(hSession), where hSession is the session ID. The session ID is returned
in the first parameter of the SmSesOpen call.

Chapter 2 Starter Set APIs

To develop a full-function speech application, you do not need to use all of the functions provided in
the SMAPI. You can use a subset of calls, known as the Starter Set SMAPIs. These calls do not use
separate header or library files.

Note:

The ViaVoice Run Time Kit contains several user interface applications that you must include with
your speech-aware application. Inclusion of these applications ensures optimal recognition performance
for your users. They also serve as reusable applications, so that you don‘t have to develop
these same functions yourself (setting up the microphone, changing ViaVoice system parameters,
enrollment, and managing the user‘s personal vocabulary).

Starter Set SMAPIs for Command and Control

When writing your command and control application, you must first establish a connection with the
speech recognition engine. Next, you direct the engine to start processing speech. Your application
interacts with the engine to set up and activate vocabularies and grammars. Most of your work is
involved in processing the recognized speech. When you are done, you disconnect from the engine.

Here are the Starter Set SMAPIs for command and control applications:

. SmOpen
. SmConnect
. SmDefineGrammar
. SmDefineVocab
. SmDefineVocabEx
. SmEnableVocab
. SmDisableVocab
. SmRequestFocus
. SmReleaseFocus
IBM SMAPI Reference

Starter Set APIs

. SmMicOn
. SmMicOff
. SmRecognizeNextWord
. SmReceiveMsg
. SmGetFirmWords
. SmGetAnnotations
. SmDisconnect
. SmClose
Establishing a Recognition Session

To establish a recognition session with the engine, use SmOpen to set up local parameters for starting
the engine and SmConnect, which actually establishes the link between your application and the
engine. You can use SmSetArg to set the input parameters to SmOpen and SmConnect (such as
language, user ID, and enroll ID), but you‘ll probably want to take the defaults using
SM_DEFAULT_* parameters.

Setting Up and Enabling Vocabularies

A vocabulary is a list of words and/or phrases that the engine uses to match speech input and translate
it into text. Your command and control application specifies the set of active words by defining and
enabling one or more vocabularies. A vocabulary can be predefined in a grammar file, or it can be
created at runtime as a dynamic command vocabulary.

By passing the name of your compiled grammar file to SmDefineGrammar, the words and phrases of
your grammar are defined to the engine. SmDefineVocab allows you to build command vocabularies
dynamically by passing a list of words and phrases that make up that vocabulary. You would also use
this call to define the names for any external references in your grammar file. SmEnableVocab
enables a vocabulary. When decoding speech, the engine searches all of the enabled vocabularies to
translate speech to text. You can have more than one vocabulary active in your application at a time.

IBM ViaVoice SDK for Windows

To improve performance (both recognition speed and accuracy), your application should narrow the
possibilities by enabling and disabling vocabularies as they are needed. You disable a vocabulary by
using the SmDisableVocab call.

Directing the Engine to Process Speech

The speech recognition engine supports both shared and parallel sessions, which means that there can
be several applications connected to the speech recognition engine at the same time, and that a single
application can have more than one connection to the speech recognition engine at the same time, too.
You should design your application so that it cooperates with other speech-aware applications for
control of the microphone. This is known as "having speech focus." An application must have speech
focus to receive recognized text; this may or may not equate to input focus. You need to ensure that
your application has speech focus when it needs it. This is done by using SmRequestFocus to request
speech focus and SmReleaseFocus to release speech focus when you‘re done.

Once you have speech focus, your application must tell the engine to start processing audio data.
SmMicOn engages the engine to start processing audio data, and SmMicOff tells the engine to stop
processing audio data.

Processing Recognized Commands

The bulk of the work in your application involves getting the recognized commands from the engine
and determining what to do with it. For a command and control application, the engine waits for your
application to direct it to start recognizing words. Use SmRecognizeNextWord to start the engine
looking for words to decode. When the engine recognizes a word from a dynamic command
vocabulary, it returns the word with alternates in the SM_RECOGNIZED_WORD message. When a
phrase is recognized from a grammar, the engine returns the set of words and annotations in the
SM_RECOGNIZED_PHRASE message. Use SmReceiveMsg to accept and process these messages.
In either case, the engine stops decoding until your application makes another
SmRecognizeNextWord call. This gives you a chance to change active vocabularies for recognizing
the next command. While halted, however, the engine continues to capture and process audio, so no
words are lost.

Disconnecting from the Engine

When your application is closing down, you must disconnect and close the session with the speech
recognition engine. To do this, use SmDisconnect and SmClose.

Starter Set SMAPIs for Dictation

The Dictation Starter Set SMAPIs will enable you to develop a dictation application that supports
commands, dictation, word-error playback and correction, and language model cache updates.

Setting Up and Enabling Vocabularies

A vocabulary is a list of words and/or phrases that the engine uses to match speech input and translate
it into text. Your application specifies the set of active words by defining and enabling one or more
vocabularies.

A dictation application must first enable a predefined domain (such as the general office vocabulary)
before the engine can use it to decode text. It does so by using the SmEnableVocab function. To have
command words recognized during dictation (such as "stop dictation"), the application must enable the
dictation vocabulary first, and then define the command vocabulary. Grammar vocabularies cannot be
active at the same time as dictation vocabularies, although you can support both dictation and
command and control within the same application. SmDefineGrammar defines a grammar
vocabulary to the engine, and SmDefineVocab defines a dynamic command vocabulary.
SmEnableVocab enables all types of vocabularies (dictation, grammar, and dynamic command).

IBM SMAPI Reference

Starter Set APIs

To improve performance (both recognition speech and accuracy), your application should narrow the
possibilities by enabling and disabling vocabularies as they are needed. You disable a vocabulary by
using the SmDisableVocab call. You can also use SmUndefineVocab to delete a dynamic command
vocabulary, but it must have been disabled first.

Directing the Engine to Process Speech

Processing Recognized Text

The bulk of the work in your application involves getting the recognized text from the engine and
determining what to do with it. For a dictation application, the engine waits for your application to
direct it to start recognizing words. Use SmRecognizeNextWord to start the engine looking for words
to decode. If the engine recognizes a word from a dictation vocabulary, the available decoded words
are sent to the application in an SM_RECOGNIZED_TEXT reply message. The
SM_RECOGNIZED_TEXT reply message provides a list of firm and infirm words. Use
SmReceiveMsg to receive messages from the engine. The engine continues decoding words as they
are spoken. SmEventNotify requests that your application be notified when the engine completes
decoding all of the audio up to the point of the call.

Commands are handled as described in the preceding section, "Processing Recognized Commands".

IBM ViaVoice SDK for Windows

When a word is recognized, there is a reply structure generated which you can access via function
calls. This allows you to access both firm and infirm words. When your application is notified that a
word is recognized, use SmGetFirmWords and SmGetInfirmWords to retrieve the list of words from
the reply message.

The engine continues decoding speech after a word is recognized during dictation. There are times
your application may need to halt the engine during dictation recognition; for example, while setting
new context or adding pronunciations. To do this, use SmHaltRecognizer, which will temporarily halt
recognition. A subsequent SmRecognizeNextWord call restarts the recognition process.

SmNewContext is called when dictation begins at a new location in the document. Context refers to
the previous and following words, which are used to decode the current word.

If the engine recognizes a word from a command vocabulary, the word is sent to the application in an
SM_RECOGNIZED_WORD reply message. The engine halts and waits for further instruction from
the application. Use SmGetFirmWords on SM_RECOGNIZED_WORD to get the recognized text
from the engine.

Correcting Errors

Correcting misrecognized words and improving recognition by updating personal data files are key
functions of dictation applications. Use SmPlayWords to play back previously spoken words or
phrases to the user. This can be of great help to the user in the correction process. Use
SmQueryAlternates to provide alternative choices when incorrectly recognized words have been
detected by the user. SmWordCorrection corrects a misrecognized word. It notifies the engine that a
word or sequence of words was corrected by the user. It can be used to update the user‘s text
vocabulary, word-usage model, and pronunciation pool.

Since the data that the engine stores can be resource intensive, use SmDiscardData to discard audio
and error correction data for recognized words that are not referenced again. This can conserve speech
recognition engine disk space requirements.

Disconnecting from the Engine

When your application is closing down, you must disconnect and close the session with the speech
recognition engine. To do this, use SmDisconnect and SmClose.

SmAddToVocab

Purpose

SmAddToVocab adds words to a vocabulary.

This function adds words to predefined vocabularies or to a vocabulary previously created by
SmDefineVocab. SmAddToVocab can be used to dynamically change command vocabularies
within an application. If any of the specified words do not have an existing pronunciation, the call
returns the list of words without pronunciations. Missing pronunciations must be added by using the
SmAddPronunciation function. Pronunciations exist for all words in the predefined vocabularies
and for words added by the user. For a predefined vocabulary the words are added in the user‘s
personal pronunciation area of the vocabulary.

This call is valid only when the speech recognition engine is not decoding speech to text.

If a specified word does not exist in the current pool, the backup dictionary will be searched. If the
word is found in the backup dictionary, it will be added to the temporary pool, except that when
SmAddToVocab specifies a dictation vocabulary such as “text,” the word will be added to the
personal pool.

Syntax

int SmAddToVocab (char *vocab, short nvocwords, SM_VOCWORD *vocwords[],
SM_MSG *reply);

Parameters

vocab

input - The name of the vocabulary to which words are added.

nvocwords

input - The number of words added to the vocabulary, up to the limit defined by

SM_MAX_WORDS.

vocwords

input -The spellings of the words added to the vocabulary.

input/output -The pointer to a reply structure or to SmAsynchronous, indicating that the call is

made asynchronously.

SmDefineGrammar

Purpose

SmDefineGrammar defines a grammar-based vocabulary.

This function dynamically defines a new vocabulary that can be enabled through the
SmEnableVocab function, along with dynamic command vocabularies defined through
SmDefineVocab. The vocabulary content is specified by a precompiled FSG file, produced by the
grammar compiler.

Like SmDefineVocab, SmDefineGrammar returns a list of grammar words that don‘t have
pronunciations. Unlike SmDefineVocab, if any pronunciation is missing, SmDefineGrammar
fails with a return code of SM_RC_NOT_INVOCAB, since recognition of a grammar network
with missing pronunciations is not well defined. Use SmGetVocWords to retrieve the list of
missing words.

If external lists are missing (for example, there was no SmDefineVocab before the
SmDefineGrammar), SmDefineGrammar will also fail. This time, the return code is
SM_RC_MISSING_EXTERN. The names of the external lists are returned as if they were words
without pronunciations, and can also be obtained with SmGetVocWords.

Since missing externs is really a program logic error, these are checked and returned before
determining if any words are missing pronunciations. So, if both externs and words are missing,
you first get SM_RC_MISSING_EXTERN. When that is fixed, you get
SM_RC_NOT_INVOCAB.

Note that pronunciations can be found in the user‘s personal pool, application-specific pools
(created by Dictionary Builder) or the base domain pool. If a specified word does not exist in the
current pool, the backup dictionary will be searched. If the word is found in the backup dictionary,
it will be added to the temporary pool, except that when SmAddToVocab specifies a dictation
vocabulary such as “text,” the word will be added to the personal pool.

Syntax

int SmDefineGrammar (char *vocab, char *grammar, long options,
SM_MSG *reply);

Function Calls to the Speech Recognition Engine

SmDefineVocab

Purpose

SmDefineVocab defines a new vocabulary.

This function dynamically creates a new vocabulary that can later be used by calling the
SmEnableVocab function. The vocabulary created by SmDefineVocab consists only of the words
specified in the call with all words receiving an equal voice model weighting. This function can be
used to dynamically create command vocabularies in an application. If any of the specified words
do not have an existing pronunciation, the call returns a list of words without pronunciations.
Pronunciations can be found in the predefined vocabulary and in the user‘s personal vocabulary.
Predefined vocabularies are not dynamic. Dynamic vocabularies are intended for command
vocabulary recognition.

SmDefineVocab takes more time to execute than SmEnableVocab and SmDisableVocab;
therefore, it is more efficient to define a vocabulary once and enable/disable frequently rather than
to define multiple times.

This call is valid only when the speech recognition engine is not decoding speech to text. For
examples of conditions when the engine is not decoding speech to text, see "Setting Up
Vocabularies" in the SMAPI Developer‘s Guide.

Syntax

int SmDefineVocab (char *vocab, short nvocwords, SM_VOCWORD *vocwords[],
SM_MSG *reply);

Parameters

vocab

input -The name of the new vocabulary.

nvocwords

input -The number of words in the new vocabulary. Limited to SM_MAX_VOCWORDS.

IBM ViaVoice SDK for Windows

Function Calls to the Speech Recognition Engine

SmDiscardData

Purpose

SmDiscardData discards audio and error-correction data.

This function discards audio data and error-correction information for recognized words that are
not referenced again, thus conserving speech recognition engine disk space (reference
“SmDisconnect” on page 74 for the SmNdiscardSessionData speech attribute used).

SmDiscardData works on the granularity of utterances (between SmMicOn and SmMicOff) and
discards utterance files owned by the application. Ownership is established by the application that
turned the microphone on to create the utterance. An application can guarantee ownership of its
data by toggling the microphone Off and On when it receives focus.
