google-speech | node.js module for Google speech systems | Speech library

In my project I am developing a websocket server in golang which is controlling asterisk channel via ARI and performing live audio transcription on the same channel with google-speech-api. On connection I want to save audio from an asterisk channel to file while simultanously sending audio to google and get a transcript. Audio is being sent by asterisk audiofork app so that I can manipulate channel with ARI while audio is streamed on another thread.

The problem is that when I send frames to google I get EOF error on the first and every consecutive frame I send from my server but when I convert binary file with saved frames to wav using sox I get recording of audio on the channel so the frames send by audiofork aren't corrupted. Can anyone give me any advice how to make google-speech-api cooperate with me?

I'm using Google Cloud Text-to-speech to synthesize speech from text. How can I specify the region for the API calls? This is similar to this question Specify Region for Google Speech API? but my question is for text-to-speech, not speech-to-text.

For speech-to-text there wasn't an available endpoint in Europe but there is one now: https://cloud.google.com/speech-to-text/docs/endpoints

I can't find the same type of endpoint documentation for text-to-speech, the closest I find is this page: https://cloud.google.com/text-to-speech/docs/reference/rest that specifies a single endpoint: https://texttospeech.googleapis.com

Does this mean that I cannot keep the text-to-speech requests within Europe? It could also be that the region is fetched from the Google Cloud project region or something like that but I cannot find such an option.

I'm trying to transcribe a German podcast which I have both on my pc and my Google Storage bucket. I'm using this tutorial as a reference.

Here's my code:

I've been pretty stuck on this problem for a few days now, praying that someone will be able to point me in the right direction.

I have a stream of Opus buffers as encoded by https://github.com/discordjs/opus

I want to send these to the google speech to text api which require them to be encapsulated in ogg containers: https://cloud.google.com/speech-to-text/docs/reference/rpc/google.cloud.speech.v1#audioencoding

I'm trying to use this library: https://github.com/TooTallNate/node-ogg

Here is what I'm trying:

I'm trying to execute google-speech-to-text from apps script. Unfortunately, I cannot find any examples for apps script or pure HTTP, so I can run it using simple UrlFetchApp.

I created a service account and setup a project with enabled speech-to-text api, and was able to successfully run recognition using command-line example

curl -s -H "Content-Type: application/json" \ -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \ https://speech.googleapis.com/v1/speech:recognize \ -d @sync-request.json

which I can easily translate to UrlFetchApp call, but I don't have an idea to generate access token created by

gcloud auth application-default print-access-token

Is there a way to get it from apps script using service account credentials?

Or is there any other way to auth and access speech-to-text from apps script?

I have a need to do some real time transcriptions from twilio phone calls using Google speech-to-text api and I've followed a few demo apps showing how to set this up. My application is in .net core 3.1 and I am using webhooks with a Twilio defined callback method. Upon retrieving the media from Twilio through the callback it is passed as Raw audio in encoded in base64 as you can see here.

https://www.twilio.com/docs/voice/twiml/stream

I've referenced this demo on Live Transcribing as well and am trying to mimic the case statement in the c#. Everything connects correctly and the media and payload is passed into my app just fine from Twilio.

The audio string is then converted to a byte[] to pass to the Task that needs to transcribe the audio

I have a problem when trying to generate a release version of my app. It gives a strange error
