2. Put the credential json for Google Cloud Text-to-Speech API in your robot

Installation

For python2.7, you need to use google-cloud-texttospeech==1.0.1.

sudo pip install google-cloud-texttospeech==1.0.1

Usage

Launch sound_play with Google Cloud Text-to-Speech

roslaunch google_cloud_texttospeech google_cloud_texttospeech.launch credential:=/your/credential/json/path

Say something

For python users

import rospy
from sound_play.libsoundplay import SoundClient

rospy.init_node('say_node')

client = SoundClient(sound_action='robotsound', sound_topic='robotsound')

client.say('hello!')
client.say('こんにちは', voice='ja')

You can change the voice by changing the voice_name. Look at the following website for further details. Google Cloud Text-to-Speech Supported voices and languages

We can use standard and WaveNet voices. WaveNet voices are higher quality voices with different pricing; in the list, they have the voice type ‘WaveNet’.

You can also choose the language by specifying the language code. ja for Japanese, de for German, etc.

client.say('你好', voice='cmn-TW-Wavenet-A')
client.say('Hallo', voice='de')

$ roseus
(load "package://pr2eus/speak.l")

(ros::roseus "say_node")

(speak "JSKへようこそ。" :lang "ja-JP-Wavenet-B" :wait t)
(speak "Welcome to JSK." :lang "en-US-Wavenet-A" :wait t)
(speak "欢迎来到 JSK" :lang "cmn-TW-Wavenet-A" :wait t)

Tips

By default, generated audio files are stored at $HOME/.ros/google_cloud_texttospeech/cache. If you want to change the cache directory, please set GOOGLE_CLOUD_TEXTTOSPEECH_CACHE_DIR as an environment variable.

If you don’t want to cache the files, please set GOOGLE_CLOUD_TEXTTOSPEECH_CACHE_ENABLED=false.
