Process
Simple Steps, Amazing Results
From text to lifelike conversations in minutes
Input Your Script
To use Dia TTS, simply type or paste your text into the input field. The system recognizes speaker tags like [S1], [S2] to differentiate between speakers in a conversation. You can also include non-verbal cues such as (laughs) directly in the text.
Optional Audio Prompt
For more personalized output, you can upload a reference audio file. This guides the voice style or allows for voice cloning, giving you greater control over the final output.
Generate Speech
Once your script is ready, click the "Generate" button. Dia TTS processes your input and creates audio based on the provided text and any additional parameters you've set.
Preview and Download
After generation, you can listen to the created audio directly in the interface. If satisfied, you can download the file for use in your projects. This step allows for quality control before finalizing the output.
