MOSS-TTS-Nano

MOSS-TTS-Nano

Turns text into speech with a tiny 0.1B-parameter model that can run on a CPU, supports voice cloning and covers 20 languages. It suits developers who add speech to local or web apps.

About

What it is: MOSS-TTS-Nano is an open-source text-to-speech model from MOSI.AI and the OpenMOSS team. It has only 0.1B parameters and is built for realtime speech. It can run on a CPU with no GPU. The setup is light enough to try locally, serve on the web or build into a small product.

Who it suits: It suits developers who want speech output without a heavy GPU setup. People who clone voices should use only voices they have the right to use.

Industry | Who uses it | How they use it | Example
Software | App developers | Add spoken replies to a local or web product | Serving speech to a web page from your own machine
Content creation | Creators | Read long text aloud, with voice cloning from a reference clip | Narrating a long article in a cloned voice you own
Education | Language teachers | Generate speech in several languages | Producing spoken examples in Japanese or Spanish
Research | Speech researchers | Study a small audio-tokenizer-plus-LLM design | Testing realtime latency on a CPU

People who need the highest studio quality can skip it, since the card aims for good-enough quality in realtime products.

Where to use it:

• A CPU-only computer, since the card says streaming can run on a 4-core CPU
• A local web demo started from the project's app script
• A command line, for generating speech or serving it
• Windows, macOS or Linux, with Python

Use case | Who | What they get back
Voice cloning | Creators | Speech in a cloned voice, with long text split into chunks
Local web demo | Developers | A browser page that speaks text you type
Command line serving | Developers | A service that produces speech on request

How to set it up:

• Python on your computer
• A CPU is enough, though a GPU is optional
• The project's code, which provides the scripts and the packaged command line

1. Install the Hugging Face hub package.
2. Download the model files.
3. Set up the environment as the model card describes.

pip install -U huggingface_hub

hf download OpenMOSS-Team/MOSS-TTS-Nano-100M

How to use it: The card names four ways to run it. One script does voice cloning, one starts a local web demo, and the packaged command line can generate speech or run a server. The options each one takes are not in the text provided here.

python infer.py
python app.py
moss-tts-nano generate
moss-tts-nano serve

Tool | What it does
infer.py | Runs voice cloning from a script
app.py | Starts a local web demo
moss-tts-nano generate | Generates speech from the command line
moss-tts-nano serve | Runs the model as a local server

Example: You start the local web demo, type a short paragraph and play back the result. With voice cloning, you supply a reference clip of a voice you may use and read a long text in that voice. The card says long input is split into chunks automatically.

For newcomers and experts: A text-to-speech model reads written text aloud. A first small step is to try the hosted demo the card links, then run the web demo on your own machine.

It is a pure autoregressive design that pairs an audio tokenizer with a language model. Output is 48 kHz in two channels, and streaming inference keeps the delay to the first audio low. The card lists 20 languages, including Japanese, Korean, Arabic, Russian, Polish, Portuguese and Swedish.

You enter text
Language model predicts audio tokens
Audio tokenizer decodes them to sound
Speech streams out at 48 kHz

Good to know:

• License: Apache 2.0.
• Cost to run: none named for local use. The card also links a hosted studio and API docs, with no price given.
• Data it reaches: it downloads files from the Hugging Face Hub. Your text and any reference voice clips stay on your machine.
• Not for: cloning voices you have no right to use.
