Think tank
Why 8 kHz Indian telephony is a different problem from studio audio.
Most public speech models are trained on clean, read speech. A sales call in India is noisy, 8 kHz, and often switches language inside one sentence.
Hexta Engage treats Hinglish and Taminglish as native speech, not as a translation step added after the call.
The practical test is not a leaderboard. It is whether the caller stays on the line and the outcome lands in the CRM.
