I am using Google Cloud Text to Speech modules in Integromat for my Adalo app. I want to have better audio quality, so I've already switched to WaveNet and increased the Sample Rate to 48000 Hertz, but it still has pretty bad quality. What can I do? Every idea is much appreciated, thanks in advance!

Best regards, Ben

You probably need to specify the effectsProfileId, as per the documentation at https://cloud.google.com/text-to-speech/docs/audio-profiles

const effectsProfileId = ['telephony-class-application'];

const request = {
  input: {text: text},
  voice: {languageCode: languageCode, ssmlGender: ssmlGender},
  audioConfig: {audioEncoding: 'MP3', effectsProfileId: effectsProfileId},
};

The quality of the speech waxes and wanes according to what sort of device you say you're playing the resulting audio through.

Convert your data to the recommended encoding mentioned by Google . Us e the same format as mentioned in Google docs like Flac format. That will give a proper accuracy. Use stereo recording ,separate Chanel's for speakers .
