Dimits - Python Bindings for Piper TTS

Dimits is a Python library that provides an easy-to-use interface to the Piper text-to-speech (TTS) system. It utilizes the powerful Piper TTS engine, which is optimized for Raspberry Pi 4, to generate high-quality synthesized speech.

Features

• Simple Python bindings for Piper TTS
• Support for multiple languages and voices
• Compatible with Raspberry Pi 3/4 and desktop Linux systems

Installation 📥

You can install Dimits via pip:

pip install dimits

This will automatically install the necessary dependencies

Quick Start 🏃🏻‍♀️

Here's a simple example of using Dimits to synthesize speech:

from dimits import Dimits

# Initialize Dimits with the desired voice model
dt = Dimits("en_US-amy-low")

# Convert text to audio and play it using the aplay engine
dt.text_2_speech("Hello World", engine="aplay")

Voices 🔊

Dimits supports all the voices available in the Piper TTS system. To use a specific voice, simply provide corresponding .onnx file namepo initializing the Dimits class.

For a list of available voices and their download links, refer to the Piper TTS repository.

Usage 📃

Initializing Dimits

To use Dimits, first create an instance of the Dimits class, providing the path to the desired voice model:

from dimits import Dimits

dt = Dimits("en_US-amy-low")

Synthesizing Speech

To synthesize speech and play on the go, simply call the text_2_speech method, providing the text to be synthesized and the desired engine:

dt.text_2_speech("This is a test.",engine='aplay')

on other hand to synthesize speech and save it to the file, call text_2_audio_file finction providing file_name dir and format

dt.text_2_audio_file("Hello World", "hello_world", "/path/to/output/directory/", format="wav")

Changing Voices

To change the voice used for synthesis, create a new instance of the Dimits class with the desired voice model:

# dt = Dimits("en_US-amy-low")
dt = Dimits("en_US-danny-low")

TODO 📝

• Implement windows compatible executible to run the voice models
• Support for multiple audio player engine
• Benchmark
• Documentation
