str2speech 0.3.3

A powerful, Transformer-based text-to-speech (TTS) tool.

👉 str2speech

Overview

str2speech is a simple command-line tool for converting text to speech using Transformer-based text-to-speech (TTS) models. It supports multiple models and voice presets, allowing users to generate high-quality speech audio from text.

Latest

We now support Microsoft's Speech T5. This is a very lightweight model, and sounds pretty good. Try it out with this:

str2speech --model "microsoft/speecht5_tts" \
    --text "My dog is prettier than yours." \
    --output "t5test.wav"

---

We now support Spark-TTS-0.5B. This is an awesome model. Here's how you use it:

str2speech --model "SparkAudio/Spark-TTS-0.5B" \
        --text "Hello from Spark" \
        --output "sparktest.wav"

---

Added support for Sesame CSM-1B. Here's how to use it:

export HF_TOKEN=<your huggingface token>
str2speech --text "Hello from Sesame" --model "sesame/csm-1b"

---

Added support for Kokoro-82M. This is how you run it:

str2speech --text "Hello again" --model "kokoro"

This is probably the easiest way to use Kokoro TTS.

---

Added support for Zyphra Zonos. Try this out:

str2speech --text "Hello again" \
    --model "Zyphra/Zonos-v0.1-transformer" \
    --output helloagain.wav

Alternatively, you could write Python code to use it:

from str2speech.speaker import Speaker

speaker = Speaker("Zyphra/Zonos-v0.1-transformer")
speaker.text_to_speech("Hello, this is a test!", "output.wav")

str2speech will try to install Zonos if it doesn't detect it on your system. You might still have to install espeak-ng manually.

If you choose to install Zonos yourself, please run the following:

apt install espeak-ng
git clone https://github.com/hathibelagal-dev/Zonos.git
cd Zonos && pip install -e .
