This is rather typical Question. Anyhow depending on the language you are using there may be many different choices. Basically, the best option for you is to use some online cloud-based API, that will take your. In this way, your API will be accessible from any language and will take a lot of pain out of your code. Human ears are well-tuned to detecting these errors, but careful work by developers can minimize errors and improve the speech output quality.

Speech recognition provides computers with the ability to listen to spoken language and determine what has been said.

In other words, it processes audio input containing speech by converting it to text. A grammar is an object in the Java Speech API that indicates what words a user is expected to say and in what patterns those words may occur. Grammars are important to speech recognizers because they constrain the recognition process.

The basic engine state systems are described in Section 4. In this section the two state systems added for recognizers are described. These two states systems represent the status of recognition processing of audio input against grammars, and the recognizer focus.

As a summary, the following state system functionality is inherited from the javax. Recognizer focus is a major determining factor in grammar activation, which, in turn, determines what the recognizer is listening for at any time. The role of recognizer focus in activation and deactivation of grammars is described in Section 6.

A change in engine focus is indicated by a RecognizerEvent which extends EngineEvent being issued to RecognizerListeners. The following code examples monitor engine state:. Recognizer focus is relevant to computing environments in which more than one application is using an underlying recognition.

For example, in a desktop environment a user might be running a single speech recognition product the underlying engine , but have multiple applications using the speech recognizer as a resource. These applications may be a mixture of Java and non-Java applications. Focus is not usually relevant in a telephony environment or in other speech application contexts in which there is only a single application processing the audio input stream.

The recognizer's focus should track the application to which the user is currently talking. When a user indicates that it wants to talk to an application e. When speech focus is no longer required e.

For example, if a recognizer is in the middle of recognizing some speech, it will typically defer the focus change until the result is completed. The focus events and the engine state monitoring methods can be used to determine when focus is actually gained or lost.

The focus policy is determined by the underlying recognition engine - it is not prescribed by the java. In most operating environments it is reasonable to assume a policy in which the last application to request focus gets the focus.

Well-behaved applications adhere to the following convention to maximize recognition performance, to minimize their impact upon other applications and to maintain a satisfactory user interface experience. An application should only request focus when it is confident that the user's speech focus attention is directed towards it, and it should release focus when it is not required.

The most important and most complex state system of a recognizer represents the current recognition activity of the recognizer. This sub-state system is shown in Figure The typical state cycle of a recognizer is triggered by user speech. In this first event cycle a Result is typically produced that represents what the recognizer heard. Each Result has a state system and the Result state system is closely coupled to this Recognizer state system.

The Result state system is discussed in Section 6. Many applications including the "Hello World! Upon receipt of a non-speech event e. Applications in which grammars are affected by more than speech events need to be aware of the recognition state system. The following sections explain these event cycles in more detail and discuss why speech input events are different in some respects from other event types. A keyboard event, a mouse event, a timer event, a socket event are all instantaneous in time - there is a defined instant at which they occur.

The same is not true of speech for two reasons. Firstly, speech is a temporal activity. Speaking a sentence takes time. For example, a short command such as "reload this web page" will take a second or two to speak, thus, it is not instantaneous. At the start of the speech the recognizer changes state, and as soon as possible after the end of the speech the recognizer produces a result containing the spoken words. Secondly, recognizers cannot always recognize words immediately when they are spoken and cannot determine immediately when a user has stopped speaking.

The reasons for these technical constraints upon recognition are outside the scope of this guide, but knowing about them is helpful in using a recognizer. Incidentally, the same principals are generally true of human perception of speech. A simple example of why recognizers cannot always respond might be listening to a currency amount. If the user says "two dollars" or says "two dollars, fifty seconds" with a short pause after the word "dollars" the recognizer can't know immediately whether the user has finished speaking after the "dollars".

A second is a long time for a computer and complications can arise if the user clicks a mouse or does something else in that waiting period. Section 6. A further complication is introduced by the input audio buffering described in Section 6. The typical recognition state cycle for a Recognizer occurs as speech input occurs. Technically speaking, this cycle represents the recognition of a single Result.

The result state system and result events are described in detail in Section 6. At this point the result is usually empty: it does not contain any recognized words. As recognition proceeds words are added to the result along with other useful information.

Applications will often make grammar changes during the result finalization because the result causes a change in application state or context. This buffering allows a user to continue speaking without speech data being lost. The commit applies all grammar changes made at any point up to the end of result finalization, such as changes made in the result finalization events. For applications that deal only with spoken input the state cycle described above handles most normal speech interactions.

For applications that handle other asynchronous input, additional state transitions are possible. Other types of asynchronous input include graphical user interface events e. When a non-speech event occurs which changes the application state or application data it may be necessary to update the recognizer's grammars. The suspend and commitChanges methods of a Recognizer are used to handle non- speech asynchronous events. The typical cycle for updating grammars in response to a non-speech asynchronous events is as follows.

As soon as the event is received, the application calls suspend to indicate that it is about to change grammars. The grammar changes affected by this event cycle and the pending commit are described in Section 6.

Once all grammar changes are completed the application calls the commitChanges method. Finally, the Recognizer resumes recognition of the buffered audio and then live audio with the new grammars. The suspend and commit process is designed to provide a number of features to application developers which help give users the perception of a responsive recognition system.

The user has the perception of real-time processing. This minimizes the amount of data in the audio buffer and hence the amount of time it takes for the recognizer to "catch up". It also minimizes the possibility of a buffer overrun. Technically speaking, an application is not required to call suspend prior to calling commitChanges.

If the suspend call is committed the Recognizer behaves as if suspend had been called immediately prior to calling commitChanges. However, an application that does not call suspend risks a commit occurring unexpectedly while it updates grammars with the effect of leaving grammars in an inconsistent state. The three sub-state systems of an allocated recognizer shown in Figure normally operate independently.

There are, however, some indirect interactions. When a recognizer is paused, audio input is stopped. However, recognizers have a buffer between audio input and the internal process that matches audio against grammars, so recognition can continue temporarily after a recognizer is paused. Eventually the audio buffer will empty. When the recognizer is resumed, it will have the focus and its grammars will be activated for recognition. The focus state of a recognizer is very loosely coupled with the recognition state.

A grammar defines what a recognizer should listen for in incoming speech. Any grammar defines the set of tokens a user can say a token is typically a single word and the patterns in which those words are spoken. These grammars differ in how patterns of words are defined. They also differ in their programmatic use: a rule grammar is defined by an application, whereas a dictation grammar is defined by a recognizer and is built into the recognizer.

A rule grammar is provided by an application to a recognizer to define a set of rules that indicates what a user may say. Rules are defined by tokens, by references to other rules and by logical combinations of tokens and rule references.

Rule grammars can be defined to capture a wide range of spoken input from users by the progressive combination of simple grammars and rules. A dictation grammar is built into a recognizer. It defines a set of words possibly tens of thousands of words which may be spoken in a relatively unrestricted way. Hybrid and multi-cloud services to deploy and monetize 5G.
