Here’s how it all comes to life
Build accurate, authoritative audio for news reporting
Credibility is crucial to media organizations. This trust is built, in part, through accurate pronunciation of proper names, places and events. Our platform helps you tailor voice output to ensure precision in reporting.

Fine-tune custom expressions for conversational AI
Voice interaction has become ubiquitous. A big part of our daily voice interactions with conversational AI revolve around standard questions. They respond with frequently-used, fixed phrases that should be pleasant and natural. To accomplish this, our platform lets you customize text-to-speech audio output for optimized performance – including tweaking domain-specific expressions.

Perform lifelike narration for training videos and product demos
Professional narration by a voice actor adds sophistication and polish to presentations. But human narrators are costly and time-consuming to direct. This platform creates human-like audio that’s both cost-effective and time-efficient.
