retico-googletts

This project contains the incremental module for running Google Cloud TTS in a retico environment. Google TTS provides multiple languages and voices, which can be looked up here.

The current implementation of the TTS module is not strictly incremental, as a new input triggers a complete resynthesizing of the speech.

Installing

In order to properly use the Text-To-Speech module, you must install two other external software.

gcloud

This is to connect you to GCP's (Google Cloud Platform) resources and services which you can install here.

ffmpeg

This is for converting the received MP3 audio from Google's Text-To-Speech synthesizer into a PCM format which can be installed here.

After installing both external software, you can now install the package with

$ pip install git+https://github.com/retico-team/retico-googletts

GoogleTTS Example

from retico_core import *
from retico_googleasr import *
from retico_googletts import *


def callback(update_msg):
    for x, ut in update_msg:
        print(f"{ut}: {x.text} ({x.stability}) - {x.final}")


mic = audio.MicrophoneModule()
asr = GoogleASRModule(rate=16_000)
td = text.TextDispatcherModule()
tts = GoogleTTSModule(language_code="en-US", voice_name="en-US-Standard-G")
ad = audio.AudioDispatcherModule(target_frame_length=0.2)
ss = audio.StreamingSpeakerModule(frame_length=0.2)
cb = debug.CallbackModule(callback)

mic.subscribe(asr)
asr.subscribe(td)
td.subscribe(tts)
tts.subscribe(ad)
asr.subscribe(cb)
ad.subscribe(ss)

mic.run()
asr.run()
td.run()
tts.run()
ad.run()
ss.run()
cb.run()

print("Running")
input()

mic.stop()
asr.stop()
td.stop()
tts.stop()
ad.stop()
ss.stop()
cb.stop()
