DuoCast
Turn any document into a two-voice podcast you can listen to on your commute
Convert text, PDFs, DOCX files and article URLs into natural-sounding two-host podcast conversations in Chinese and English.
About this launch
DuoCast converts documents into engaging two-host podcast conversations with native-quality voices in Chinese and English. Instead of robotic text-to-speech, the tool rewrites source material into a warm dialogue where two hosts ask questions and explain to each other, making long-form content easier to follow and retain while listening.
You can paste text directly, upload PDF or DOCX files, or drop in article URLs. The free preview generates a 3-minute sample of any document, while the Pro plan ($12/mo) offers unlimited full-length episodes up to 50,000 characters with MP3 downloads and priority processing. A credit pack option ($9) provides 20 episodes without subscription.
The service uses self-hosted speech synthesis models tuned for natural pronunciation in Chinese and Japanese, avoiding per-character metering that would truncate longer documents. Episodes are formatted as 5-15 minute segments with chapters and synced transcripts.
