coqui

The goal of coqui is to wrap the TTS (but really this version) Python module for translation of text to other languages.

TTS Installation

You must install the coqui-tts Python module. You’ll likely do this via:

install_coqui()

Why not the TTS module?

The https://github.com/coqui-ai/TTS repo is no longer maintained. This is where the TTS Python module comes from (when you run pip install TTS). The fork of https://github.com/idiap/coqui-ai-TTS is being actively maintained (by Idiap Research Institute), so we are using that, and the module name is coqui-tts. Note: the name of the module in Python is still TTS.

Mac OSX

In Mac OSX, you need to install some dependencies for the Python TTS version to work. We will install these via Homebrew.

brew install mecab

brew install espeak
brew link espeak

Troubleshooting

If you get something like this

    return match.group("version")
           ^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'group'

If you trace the error back, it’ll likely say something like:

    _DEF_ESPEAK_VER = get_espeak_version()

Try going to the command line and run:

espeak --version

And that will hopefully show you where the error is coming from.

Package Installation

You can install the development version of coqui like so:

To install TTS, you can either run install_coqui, which calls reticulate::py_install(), If you already have a conda environment enacted, use reticulate::py_install or simply install_coqui:

library(coqui)
install_coqui()

Or you can run create_coqui_condaenv(), which calls reticulate::conda_create() and creates a conda environment for coqui, named coqui.

create_coqui_condaenv()

If you use this method, you should run reticulate::use_condaenv("coqui") before enabling Python.

Example

This is a basic example which shows you how to solve a common problem:

library(coqui)

text = c(
  "Hello, my name is coqui.  I am a personal assistant to help talk to you.",
  "I hope you like how I sound!")
random_file = cq_tts(text)

text = c(
  "Hello, my name is coqui.  I am a personal assistant to help talk to you.",
  "I hope you like how I sound!")
res = cq_tts(text, path = "README_cache/example.wav")
