Frequently Asked Questions
Everything you need to know about text to speech and voice cloning with HixCodeTTSv1.
Text to Speech
Is the text to speech tool free?
Yes. Every account gets 5 free requests per day at no cost. For larger volume, character packs are available with no subscription and no expiry.
What voices are available?
Over 200 distinct AI voices across American and British accents, each tuned for natural-sounding speech.
What audio format do I get?
Generated speech is delivered as a downloadable WAV file, playable directly in your browser.
Is there a character limit per request?
Free accounts can generate up to 1200 characters per request. Paid character-pack accounts can generate up to 10000 characters per request.
How fast is generation?
Most requests complete in a few seconds, regardless of length, since generation runs on dedicated inference infrastructure rather than a local queue.
Voice Cloning
How does voice cloning work?
Upload a short reference sample (up to 15 seconds), then type any text — the cloned voice will speak it back to you.
Is voice cloning free?
Yes — every account gets 5 free cloning requests per day. Active character-pack customers also get a bundled lifetime allowance on top of that.
Whose voice can I clone?
Only your own voice, or a voice you have explicit permission to use. Cloning someone else's voice without consent is prohibited under our Terms of Service.
Why is there a sample length limit?
Voice-cloning models get no quality benefit from a longer reference clip — a short, clean sample works just as well and uploads faster.
Account & Billing
Do I need to create an account?
Yes — a free, email-verified account with your phone number lets us fairly enforce usage limits for everyone.
Do character packs expire?
No. Once purchased, your character balance never expires and carries over indefinitely.
Is this a subscription?
No. Character packs are one-time purchases — there is no recurring subscription or auto-renewal.
What happens if a generation fails?
Failed generations never count against your daily limit or character balance — you are only charged for successful audio.
