ASR - Automatic speech recognition

• Label: here you can type a brief description

• Key: your acquired license key from the console.developers.google.com account

• Language: the language you want to use for the translation

• Timeout: maximum recording duration in seconds. If -1 the considered timeout is unlimited

• Interrupt Key: special digits to exit the current recorded call

• Beep: to reproduce a beep before to record

• Record Speech: select if you want to save the voice recording used by Google ASR to turn it into text on XCALLY. Recordings will be saved in Recordings. 

• Number of seconds of silence: the number of seconds of silence that are permitted before passing through the next block, regardless of the interrupt key or timeout

The ASR saves the results in two-channel variables:

• GOOGLE_ASR_TRANSCRIPT: the result of the dictation recognition

• GOOGLE_ASR_CONFIDENCE: the precision of the recognition, between 0 and 1. Usually, values above 0.8-0.9 mean that the dictation has been correctly recognized.

• Grammar: The grammar that should be used for the recognition. Grammars can be specified as text/XML inline for built-in grammars or by using a reference to an external file/URI.

If you need to use the multiple grammar, the value of the first grammar must be separated from the second one using a character defined (e.g.: grammar-a%grammar-b, defining the % as a delimiter in the options field gd):

LumenVox provides the following built-in grammars:

Options:

Options control details about the recognition. Valid options are:

• p - Profile to use in mrcp.conf

• i - Digits to allow recognition to be interrupted with. Set this to "none" to allow LumenVox to process the DTMF using a DTMF grammar. Otherwise, if "any" or other digits specified, recognition will be interrupted and the digit will be returned to dialplan.

• f - Filename to play while recognition occurs (if empty or not specified, no file is played)

• t - The recognition timeout (in milliseconds). This is the total amount of time a caller has to speak.

• b - Barge-in value (no barge-in=0, ASR engine barge-in=1, Asterisk barge-in=2). LumenVox strongly recommends allowing the ASR to perform barge-in instead of Asterisk.

• gd – The grammar delimiter. Defaults to a comma.

• ct - The confidence threshold (0.0 - 1.0). If a recognition result has a confidence score below this value, it will be returned as "no match." Defaults to 0.5.

• sl - The barge-in sensitivity level (0.0 - 1.0). The higher this number, the easier it is to barge-in. Defaults to 0.5.

• sva - Speed vs. accuracy, set on a scale of 0.0 - 1.0. The higher this number, the faster (and less accurate) recognitions will be. Defaults to 0.5.

• nb - N-best list length. Defaults to 1; increase this value if you wish to get more answers back from the recognizer.

• nit - No input timeout. This is the amount of time the caller has to start speaking before the recognizer returns a no-input result.

• sct - Speech Complete Timeout. This is the amount of time, in milliseconds, LumenVox must detect silence after a user stops speaking before the recognizer begins processing the utterance. Set this lower for single word utterances and higher for longer utterances. In most cases, a value of 800 is correct.

• dit - DTMF interdigit timeout

• dtt - DTMF terminate timout

• dttc - DTMF terminate characters

• sw - Save Waveform (true/false)

• nac - new audio channel (true/false)

• spl - speech language (en-US/en-GB/etc.). If a language is declared in a grammar (it should be) this will be ignored.

• cdb - clear DTMF buffer (true/false)

• mt - media type

• iwu - input waveform URI (only applies to MRCPv2). Not supported by LumenVox.

• sint - Speech Incomplete Timeout. Not supported by LumenVox.

• rm - Recognition Mode. Not supported by LumenVox.

• hmaxd - hotword max duration. Not supported by LumenVox.

• hmind - hotword min duration. Not supported by LumenVox.

• enm - early no match (true/false). Not supported by LumenVox.

You are not required to supply any options. Multiple options can be provided by joining options with an ampersand, e.g. f=sayHelloWorld&t=5000
