After successfully executing a code to generate audio response from the API, cloud textToSpeech response in base64. How do i make this play as an audio in my workflow

Hey @incalculable-judge-70838, while you can add an audio card and use a URL for the audio source, I'm not sure there's a way to auto-play the clip.

Thanks for your insight but how do you think i can extract the audio source Url and use for a audio card

the API response for your TTS API has a field

audioContent

. In that same code block, you can make a new workflow var and fill it with that value like:

js
workflow.audioContent = `${endpoint}${response.audioContent}`

Note that the value is a relative URL (it starts with // instead of https://) so that means it needs to be appended onto whatever endpoint it is that you're querying. Check out that service's API documentation, they probably have an example you can copy/paste from.

Im using google cloud textToSpeech can i share the code i executed?

sure

const textToSpeech = async (text, languageCode = 'en-US') => { const url = 'https://texttospeech.googleapis.com/v1/text:synthesize'; const apiKey = 'API-Key'; // Replace with your actual API key const response = await axios.post( url, { input: { text }, voice: { languageCode }, audioConfig: { audioEncoding: 'MP3' } }, { headers: { 'X-Goog-Api-Key': apiKey } } ); const audioContent = _.get(response, 'data.audioContent'); return audioContent; }; // Usage: const audioContent = await textToSpeech('fine thanks');

huh, looking at the documentation, the returned value is a string of bytes, not a URL.... I don't know how to process that 😅

Oh yeah! That is absolutely correct!

hey were you able to find a solution to this? im running into the same problem

Not yet… had to switch to another provider of that function but still enjoying botpress otherwise and im looking forward to getting that the solution to the functionality here on botpress

ok nice! thanks for the quick response. if you dont mind sharing, what other provider did you use?
