Audio Playground

The Audio Playground is a dedicated space for testing and experimenting with GPUStack’s text-to-speech (TTS) and speech-to-text (STT) APIs. It allows users to interactively convert text to audio and audio to text, customize parameters, and review code examples for seamless API integration.

Text to Speech

Switch to the "Text to Speech" tab to test TTS models.

Text Input

Enter the text you want to convert, then click the Submit button to generate the corresponding speech.

text-to-speech

Clear Text

Click the Clear button to reset the text input and remove the generated speech.

Select Model

Select an available TTS model in GPUStack by clicking the model dropdown at the top-right corner of the playground UI.

Customize Parameters

Customize the voice and format of the audio output.

Tip

Supported voices may vary between models.

View Code

After experimenting with input text and parameters, click the View Code button to see how to call the API with the same input. Code examples are provided in curl, Python, and Node.js.

Speech to Text

Switch to the "Speech to Text" tab to test STT models.

Provide Audio File

You can provide audio for transcription in two ways:

  1. Upload an audio file.
  2. Record audio online.

Note

If the online recording is not available, it could be due to one of the following reasons:

  1. For HTTPS or http://localhost access, microphone permissions must be enabled in your browser.

  2. For access via http://{host IP}, the URL must be added to your browser's trusted list.

    Example: In Chrome, navigate to chrome://flags/, add the GPUStack URL to "Insecure origins treated as secure," and enable this option.
