What CSV format does Batch TTS accept?

A simple CSV file with one text line per row, saved in UTF-8 encoding. No header row is required, but if you include one, name the column 'text'. Extra columns are ignored.

Can I use different voices for different rows?

Yes. Toggle 'Cycle through multiple voices' to pick 2-4 voices and have rows alternate through them automatically. Or after uploading your CSV, use the per-row voice dropdown to override any specific row.

Which languages does Batch TTS support?

Over 140 languages, including English (US, UK, AU, IN), Hindi, Spanish, French, German, Portuguese, Chinese (Mandarin, Cantonese), Japanese, Arabic, Russian, Korean, Turkish, and many more, including Microsoft's Multilingual voices that speak multiple languages from one voice character.

Are the generated MP3s licensed for commercial use?

Yes. All audio generated on paid AccentGenerator plans is licensed for commercial use, including monetized podcasts, YouTube videos, client work, and ad campaigns.

How long are batch ZIP files kept?

Batch ZIP files are stored for 7 days after generation. You can re-download from your dashboard within that window. We recommend downloading the ZIP to your own storage right after generation for long-term keeping.
