How to play Audio from an Audio file using anvil

Anvil Q&A
25

This works. I’m just saving the mp3 and then reading it back in.

import anvil.server
from gtts import gTTS
from io import BytesIO
import os

@anvil.server.callable
def speak(audio_string):
    mp3_fp = BytesIO()
    tts = gTTS(audio_string, lang='en')
    tts.write_to_fp(mp3_fp)

    tts.save("my_file.mp3")

    with open('my_file.mp3', 'rb') as f:
        data=f.read()

    tts_blob = anvil.BlobMedia('audio/mpeg', data, name='audio.mp3')
    os.remove('my_file.mp3')

    return tts_blob
