This is the speech-to-text Flask app that receives requests from the Phonograph game I made for Godot Wild Jam #35.

speech-to-text-phonograph.py

from flask import Flask, request
import speech_recognition as sr
import uuid
import wave

app = Flask(__name__)

@app.route('/', methods = ['GET'])
def index():
    return "hello world"

@app.route('/stt_test', methods = ['GET'])
def stt_test():
  return get_text_from_speech()

@app.route('/stt', methods = ['GET'])
def get_stt():
  data = bytes(bytearray.fromhex(request.get_data(as_text=True)))
  return get_text_from_speech(data)

def get_text_from_speech(data):
  r = sr.Recognizer()
  id = str(uuid.uuid4())
  wav_file_name = "{}.wav".format(id)
  with wave.open(wav_file_name, "wb") as wav_file:
    wav_file.setnchannels(2)
    wav_file.setsampwidth(2)
    wav_file.setframerate(44100)
    wav_file.writeframesraw(data)

  audio_file = sr.AudioFile(wav_file_name)
  with audio_file as source:
    audio = r.record(source)
    text = r.recognize_google(audio)
#    text = r.recognize_sphinx(audio)
  return text

if __name__ == '__main__':
    app.run(port = 5000)
