Ethan

Ethan is a male English AI voice rated B+ on the OfflineTTS quality scale. Speech synthesis runs in your browser with no signup or per-character fees.

Voice character: Calm, Steady

Best for: General purpose

Quality rating explained: B+ is a catalog discovery label, not a measured MOS score, a public leaderboard position, or a guarantee for your script. Audition names, numbers, pacing, and chunk joins before publishing.

The Ethan voice runs on Pocket TTS (100M parameter model) with on-device audio synthesis. After model assets download, speech is generated locally in your browser.

Reviewing English text with this preset: American English is stress-timed, so an unnatural emphasis can make an otherwise clean render sound wrong. Check contractions, acronyms (spoken as letters or as a word), dates, and dollar amounts, and keep one sentence per line when a long script starts to drift.

Grade context: A B+ grade marks a solid preset with a small number of audible weaknesses, usually around pacing or short-word clarity rather than intelligibility.

What the browser downloads: Pocket TTS bundles about 146 MB of assets and runs a 100M parameter model in the tab. The first generation downloads the bundle, later visits reuse the browser cache, and clearing site data removes it.

Asset identity: this preset maps to the cached asset fingerprint ky1410, so it can be told apart from a same-named voice on another engine even when the label in the picker looks identical.

Other English voices: Heart (female, grade A), Bella (female, grade A-), Nicole (female, grade B-). Switching between them on the same sentence is the fastest way to hear whether one suits the script better.
