Common Questions About AI Voice Generation
Learn more about creating professional voice overs with CastReader
What is an AI Voice Generator?+
An AI voice generator converts written text into spoken audio. CastReader combines speech with synchronized highlighting and auto-scroll so you can listen and follow the text at the same time.
Is CastReader really free to use?+
The standard voice tool has a free allowance. For personal voice cloning, a signed-in account may create multiple voices and play their fixed previews. Applying them to arbitrary Read Aloud or Explain text requires Pro.
Can I use the AI voices for YouTube or commercial projects?+
Use generated audio only where you have the necessary rights. Personal voice cloning requires the voice owner's explicit consent; CastReader does not grant rights to someone else's identity or recordings.
How does Voice Cloning work?+
In the CastReader app or extension, you read a displayed prompt and record a short, clear sample. We validate the recording and create a private personal voice. The web tool does not accept arbitrary third-party audio uploads.
What languages are supported?+
The standard voice catalog covers many languages. Personal cloned voices currently generate in 10 languages: English, Chinese, Japanese, Korean, Spanish, French, German, Italian, Portuguese and Russian. A voice created from one supported recording language can be used in all 10.
Is my text and voice data private?+
Personal voice references and fixed previews are stored privately and encrypted. They are not published to the public voice catalog. You can delete a voice, but deleting it does not reset the one-time free creation.
What counts toward the Pro 120-minute personal-voice allowance?+
Only successfully generated audio duration counts. Playback, the fixed free preview, failed jobs and cancelled jobs do not. The allowance resets with the entitlement period; trialing and paid Pro users follow the same rule.
What happens when the 120 minutes are used?+
Personal-voice generation pauses until the monthly reset. Your saved voice remains available, and you can keep using standard CastReader voices. CastReader will not silently replace the selected personal voice.
