What is Dia-1.6B?

Dia-1.6B is a text-to-speech (TTS) model from Nari Labs, converting text input into natural-sounding speech. Its unique ability to generate realistic dialogue, complete with nonverbal expressions, sets it apart.

Accessing Dia-1.6B

Dia-1.6B offers two access methods:

1. Hugging Face API and Google Colab: This method requires a Hugging Face API key and coding in a Google Colab notebook. A T4 GPU (with 10GB VRAM) is necessary for optimal performance.

2. Hugging Face Spaces: A no-code interface for interactive use, allowing you to input text and even audio prompts to influence the generated voice.

Using Hugging Face API and Google Colab

1. Obtain a Hugging Face API Key: Generate a key at https://www.php.cn/link/ae714b2895215ee6c844a04374bde7fb, enabling necessary permissions (see image below).

2. Set up Google Colab: Create a new notebook, add your API key as a secret named "HF_Token," and switch to a T4 GPU runtime.

3. Clone and Install: Clone the Dia Git repository (!git clone https://github.com/nari-labs/dia.git) and install required packages (!pip install ./dia and !pip install soundfile). Restart the runtime after installation.

4. Run the Code: The provided code snippet (see original article) demonstrates model initialization, text input, inference, and audio output. The generated audio will be human-like, even incorporating nonverbal elements. Note that results may vary due to the model's non-deterministic nature. Setting a seed can improve reproducibility.

Using Hugging Face Spaces

The Hugging Face Spaces interface (https://www.php.cn/link/6cf7e97db3595534ba7691cdc074c2a5) provides a user-friendly way to interact with the model. Input text and optional audio prompts can be used to shape the generated speech. Note that some users have reported occasional errors; experimenting with different inputs may be necessary.

Dia-1.6B Usage Tips

• The model isn't fine-tuned to a specific voice; each generation produces a unique voice. Seed fixing can help with consistency.
• Dia uses a 44.1 KHz sampling rate.
• Always restart the Colab notebook after installing libraries.
• Experiment with input text and audio prompts on Hugging Face Spaces to overcome potential errors.

Summary

Dia-1.6B offers a promising approach to text-to-speech, excelling in natural speech generation and nonverbal communication. While voice consistency isn't guaranteed, its capabilities are impressive. Remember to use this powerful tool responsibly.
