How to set up Google account to use text-to-speech (TTS) voices

Google offers a whole range of different text-to-speech voices in different languages as cloud service.

The PixVis Video Dubber converts text to speech just before playing the caption. It invokes Google cloud service to get the audio stream.

Currently, Google offers this service for 1 million characters of Wavenet voices and for 4 million characters of Standard voices each month for free.

Higher volumes may incur fees. See the price list for more information:
