The challenge
The problem for creators who need voice content
Hiring voice actors for every ad video, podcast, or product intro costs time and money, especially when content needs frequent revisions. Building multi-character dialogue is even harder because it requires recording multiple people. In the other direction, manually transcribing meetings, interviews, or videos into text or subtitles is also time-consuming.
The solution
The solution: one tool for both voice generation and transcription
VONIA runs on dedicated GPU infrastructure, generating speech from text with 30 built-in preset voices, cloning a business's or KOL's own voice from a 3–10 second audio sample for reuse across future content, designing a new voice by attributes (gender, age, pitch, regional accent) without needing an audio sample, and building multi-character dialogue merged into a single file. In the other direction, VONIA transcribes audio/video into timestamped text and exports SRT subtitle files.
Who it's for
