☁ Google TTS
- Get an API key — free, via the "How to get a free API key" link in that panel. Covers 1 million characters a month at no cost.
- Paste and save your key — it's stored only in your browser, never sent anywhere else.
- Pick a voice type — WaveNet and Neural2 sound the most natural. Studio is premium (paid beyond free tier). Standard is more robotic but free.
- Choose a language and specific voice, then type your script and hit SPEAK.
B Browser TTS
- Uses your computer's own built-in voices — no API key, no setup, works instantly offline.
- Sounds noticeably more robotic than Google TTS or My Voice, but it's the fastest option with zero cost.
- Adjust rate and pitch with the +/− controls, then hit SPEAK.
V My Voice
- Start the local server on your Mac first (the Python server running in Terminal) — this page can't generate audio in your voice unless it's running.
- Check the connection dot next to "Local Server Address" — green means connected, red means the server isn't reachable.
- Record a voice sample with the RECORD NEW SAMPLE button — speak naturally for 10–30 seconds in a quiet room. You can record and keep several samples; more varied samples generally produce a richer, more natural clone.
- Delete unwanted samples anytime with the ✕ next to each one in the list.
- Type your script in the SCRIPT box, then hit SPEAK. A "Generating..." popup will appear — this can take 10–30 seconds since it's running on your Mac's processor, not a fast cloud server.
Speed & Expression Sliders
- These only affect the next generation — moving a slider does not change audio that's already been generated or is currently playing.
- Speed — how fast the voice talks. 1.00 is normal pace.
- Expression — how much natural variation and inflection the voice has. Lower values sound flatter and more consistent; higher values sound more animated but slightly less predictable.
- To hear a change, adjust the slider, then click SPEAK again.
Tip: keep the script reasonably short per generation (a paragraph or two) rather than pasting huge blocks of text — shorter passages generate faster and are easier to review before you commit to a longer piece.
