How to set vad-mode and speech-complete-timeout as builtin grammar parameters

Right now I'm setting some parameters on the grammar directly from the asterisk dialplan:

...
same => n,SpeechActivateGrammar(builtin:speech/transcribe?single-utterance=${ASR_SINGLEUTTERANCE}\;language=${ASR_LANGUAGE})
...

I would like to be able to configure the vad-mode and speech-complete-timeout parameters but it seems they are not received if passed in the same way.

How can I do this?

Has no one ever done such a thing?

Thank you Vahagn,

it seems that unlike the others, the parameter "speech-complete-timeout " is not recognized.
The same thing also happens for the "vad-mode" parameter.
Basically it seems that not all parameters can be passed in this way, or must be passed with a different name but the documentation is not clear about this.

Do you have any idea about it?

builtin:speech/transcribe?single-utterance=false;language=it-IT;speech-complete-timeout=1300

2023-08-21 08:35:30:806128 [INFO] Process RECOGNIZE Request <ec8386563fec11ee@speechrecog> [2]

2023-08-21 08:35:30:806255 [WARN] Unknown Parameter [speech-complete-timeout] <ec8386563fec11ee@gsr>

Best regards,

Hi Massimiliano,

It is true that you can pass vendor-specific parameters as input arguments to the built-in grammar. All the parameters which can be specified in that way are listed in this section. However, you should be using the standard MRCP header fields SPEECH-COMPLETE-TIMEOUT and SENSITIVITY-LEVEL for the other two parameters you referred to, per this section.
