2. Using Hailuo in VoiceScriptPlayer

In the Audio Editor of VoiceScriptPlayer,
you can synthesize speech directly from text using the Hailuo engine.
The interface is similar to COEIROINK, allowing you to synthesize multiple lines at once
and adjust each sentence’s timing and duration in the timeline.

🗣️ Basic Workflow

  1. Select the TextToSpeech Engine
    From the dropdown menu at the top, select Hailuo AI.
    If your API key is correctly registered, the connection will be established automatically.

  2. Enter Sentences
    Input multiple sentences in the timeline or text input box.
    Each sentence appears as an independent block that can be freely reordered or resized.

  1. Post-Processing Options (Optional)

4. Notes & Limitations

  • The Hailuo API is not free.
  • The web plan and API plan are separate, and
    using the web-based voice synthesis does not cover API usage fees.
  • An internet connection is required since Hailuo runs on the cloud.
  • Some voices do not support emotion settings.
  • API requests have usage limits — short sentences are recommended.
  • If responses are delayed, check the Hailuo server status or network condition.
