What happened
Arini uses Cartesia's Sonic text-to-speech model and voice cloning to power its AI receptionist for dental practices, which answers calls, schedules appointments, and provides insurance and billing information. Cartesia replaced Arini's previous main voice provider as the primary provider because of lower latency.
Summary written by usedby from the source page, in English. The figures are those of Cartesia and Arini, not ours.
- ~90ms“Sonic consistently achieves ~90ms model latency to first byte, ensuring that patient requests are promptly attended to.”
Sonic’s sub-90ms latency is more than 2x faster than Arini’s previous main provider, keeping patients engaged on calls.
For a product like ours, every additional millisecond of latency matters because it directly correlates to patients hanging up. One dropped call is upwards of $5,000 in potential revenue for our practices. We knew we had to switch to Cartesia as our main provider when we saw that it was more than twice as fast as our existing one and the immediate impact to our customers’ bottom line.
