How to Translate Videos with Multiple Speakers Without Losing Clarity

What Matters Most in Translating Multi-Speaker Videos?
To ensure interviews and podcasts remain clear and authentic after translation, providers must offer:
- Multi-speaker support – accurately separating and translating multiple voices
- Voice cloning – keeping each speaker’s own voice in other languages
- Lip sync – realistic synchronization for video podcasts and interviews
- Glossary & custom prompts – consistency in terminology and brand voice
- Scalability – ability to handle multi-hour content without restrictions
👉 Only a handful of providers worldwide can deliver all of this.
