# Voice One — the expressive voice > Voice One is eroq's expressive text-to-speech flagship: a curated roster, your own cloned voices, speed and expressiveness controls, 13 languages, MP3 out. 3 credits per 100 characters. Voice One is the studio's flagship text-to-speech engine: natural, expressive reads from a curated roster (Aria, warm and intimate; Orion, low and unhurried), from voices you clone from your own audio, or from a Character's assigned voice. Delivery is driven by punctuation and two controls — speed and expressiveness — and the output is an MP3 you can drop anywhere. ## At a glance | | | | --- | --- | | Price | 3 credits / 100 characters | | Voices | Roster (Aria, Orion) · your clones · Characters | | Languages | 13 | | Controls | Speed 0.7–1.3 · expressiveness 0–1 · punctuation | | Output | MP3 | | Access | Every account | ## Directing a read The engine reads punctuation like an actor reads a script: commas breathe, an ellipsis hesitates, a dash cuts, a question lifts. Expressiveness at 0 is a steady narration; at 1 it is theatrical. Speed stays around 1 for dialogue and drops for audiobook-style narration. The Delivery guide in the voice studio lists the six techniques with examples you can insert. ## Cloning and casting - Clone a voice from a clean recording — a minute of natural speech, no music, one speaker. - Assign a voice to a Character so every line they speak, in any scene, is the same voice. - Use `char:` as the voice in the API to speak as a Character. ## Starting points - **Late-night radio** — It's past midnight, and the city's finally quiet. Stay with me a while… we've got nowhere else to be. - **Whispered aside** — Don't look now — but I think they're watching us. Act natural. Smile. There. - **Audiobook opener** — Chapter one. The letter arrived on a Tuesday, which was, she would later say, the first thing that went wrong. ## FAQ ### How much does text-to-speech cost on eroq? 3 credits per started block of 100 characters on Voice One, 2 on Voice Turbo.
