What Sets Us Apart
Designed for Indian Conversational Speech
Code-Mix Excellence
Bilingual Phrases, Zero Awkward Transitions.
Traditional TTS engines stumble awkwardly when switching languages. Our engine natively understands bilingual phrases—pronouncing names, addresses, and English terms embedded inside Indic sentences smoothly without requiring complex SSML language-switching tags.
- ✓Hinglish: "Hi Ramesh, aapka payment kal due hai. Would you like to pay now?"
- ✓Tanglish: "Tomorrow 4 pm confirm pannalaama? I'll send the details."
- ✓No SSML language-switching tags required
- ✓Smooth pronunciation of names, addresses, and embedded English
Telephony Optimized
Crystal Clear Over Real Phone Lines.
Most TTS engines generate beautiful 48kHz HD audio that sounds "mushy" or robotic once compressed over a standard phone network. We optimize our synthesis specifically for 8 kHz telephony channels to preserve crisp articulation and emotional resonance over the wire.
- ✓Optimized for 8 kHz telephony channels
- ✓Crisp articulation preserved over phone networks
- ✓Emotional resonance maintained under compression
- ✓Outperforms HD-only models on real phone calls
