Whichever voices your browser and operating system provide — open the voice list in the tool to see what is installed. Indian-language voices appear only if your system has them; quality varies by device.
Your browser's built-in voices — male and female options vary by device and OS. Pick from the voice list in the tool; quality depends on your system voices.
Yes — speech rate from 0.5x to 2x in 0.1 steps and voice pitch from 0 to 2. There is no volume slider; use your device volume.
As audio, no — browser speech synthesis can't export MP3/WAV. Download your text as .txt from the tool; audio recording needs a server-side TTS service.
No. Everything runs on-device in your browser — nothing is uploaded, recorded, or stored.
