Running pushtotalk without mic

[rohitmsaxena]

I am trying to get the googlesamples-asisstant-pushtotalk project working but without using a mic. I just want to be able to type to it, not use a mic anyway.

I did everything I needed to except for the mic part and am getting this error:

Does anyone have any experience making the code run without using the mic?

If you don't want to use the mic, you can use the textinput.py sample.

Hi @Fleker , Is there any way to send text input and get a voice response from Google Assistant when connected to Raspberry Pi. I have speakers connected to Raspberry Pi but do not have the mic. I need to send the text input as we give in textinput.py and get a voice response from Google Assistant instead of the text output. Thanks.

Check textinput.py for how to use text input.

Hi @Fleker , Thanks for your response. textinput.py is working fine for both text input and text output from Google Assistant. But when I try to use features of both textinput.py and pushtotalk.py for sending text input and getting voice response from Google Assistant, I'm unable to do that. I can see this error : "Getting error: sounddevice.PortAudioError: Error querying device -1 ". (Even oushtotalk.py is getting the same error.) I think this is because I do not have a mic connected to the raspberry pi. Is it mandatory to have the mic connected to raspberry pi, even if I use text input and get voice output? I have speakers connected to the raspberry pi, but I do not have a mic connected to the raspberry pi. I am trying to send text input and trying to get a voice response. Thanks.

You may need to take a look at both textinput for getting the input, and pushtotalk for processing the output audio response that you get.
