Voice cloning questions
Clear answers about signed-in creation, fixed previews, Pro application minutes, recording, safety, and regional data boundaries.
What can I do with a free account?
After signing in, Free can create, manage, delete, and fixed-preview multiple personal voices. Fixed previews use a server-set script and do not consume the 120-minute allowance. Free cannot apply a clone to arbitrary text, Read Aloud, or Explain.
What does Pro include for personal voices?
Pro can use personal or explicitly authorized voices in Read Aloud and Explain for 120 minutes per membership-month window; the tool shows the service's exact reset date. Accounts in a Pro trial have the same voice-cloning access as other active Pro accounts.
How are the 120 minutes measured?
CastReader counts the actual duration of successfully generated cloned audio. The allowance is not a voice-creation count, text-character count, or playback count.
When do my personal-voice minutes reset?
The tool shows the exact reset date returned by the service for your current allowance cycle. It does not guess a date in the browser.
Do failed requests use my minutes?
No. Failed, cancelled, timed-out, or quality-rejected requests do not use minutes. Idempotent retries are not charged twice, and replaying cached audio does not use minutes again.
How many personal voices can I create?
All signed-in Free and Pro members can create multiple personal voices. Creation is not a Pro benefit and does not consume the 120-minute application allowance; only a concurrent creation task or a technical or recording-quality issue may temporarily prevent a new submission.
What happens when I delete one of my voices?
Deleting removes that voice and its stored reference and revokes related Voice Gifts. It does not affect your other voices or change your ability to create more.
Which languages can the same cloned voice use?
The same voice can be used for English, Chinese, German, Spanish, French, Italian, Japanese, Korean, Portuguese, and Russian. Cross-language pronunciation and naturalness vary with the language and recording quality.
Whose voice may I clone?
Only clone your own voice or a voice whose owner has given explicit authorization. For another living person, use the Voice Gift flow so they sign in, record, and authorize access themselves. Posthumous recreation is not supported.
What recording works best?
Record directly through the browser microphone for 3–30 seconds in a quiet room, using a natural pace and the prompt shown in your interface language. CastReader selects or processes a clear segment; 10–20 seconds usually gives a stronger reference.
Can I upload an existing audio recording?
No. The current public tool accepts only a direct microphone recording. It does not provide an upload flow for existing voice files.
How do I delete a cloned voice?
Open the signed-in voice-cloning tool, select the saved voice, and choose Delete voice. This deletes that stored reference and revokes related Voice Gifts without affecting your other voices.
What happens when my 120 minutes are used up?
Your voice and current selection stay saved. CastReader shows that the allowance is exhausted, displays the reset date, and offers a path to choose a standard voice. It does not silently replace your voice or show an upgrade wall to an existing Pro member.
Does a Pro trial include personal-voice use?
Yes. A trialing Pro account has the same personal-voice access as an active paid Pro account, including the 120-minute allowance for Read Aloud and Explain.
Are global and China voice data shared?
No. Global and China users, sign-ins, storage, databases, and compute are fully isolated. Accounts, libraries, voices, and voice data do not sync across regions.
Can I download audio made with my personal voice?
Pro can download successful cloned audio in tools that provide a WAV download or export. The Free fixed preview is for playback only and does not unlock arbitrary-text downloads.
Record a better voice sample
Use a quiet room
Turn off music, fans, and notification sounds. One speaker only.
Keep a natural distance
Place the microphone about 15–25 cm away and avoid touching the device.
Speak naturally
Use your normal pace and tone. Do not whisper, shout, or imitate another person.
