What is Krisp?

Krisp 2.83.4 brings Voice Translation into conference calls and lightens Accent Conversion.

Krisp is a Call Center AI platform for BPOs and enterprise contact centers, bundling Accent Conversion, Voice Translation, QA scoring, deepfake risk detection, fraud detection and conditional recording. Call Center AI became free to try in September. Release 2.83.4 on October 26 adds a Conference mode beta for Voice Translation and makes Accent Conversion sound more natural at lower CPU cost, though the source note is truncated.

What is OpenPhone?

OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.

OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.

Krisp 2.83.4 brings Voice Translation into conference calls and lightens Accent Conversion.

◆ Current state

Krisp is a Call Center AI platform for BPOs and enterprise contact centers, bundling Accent Conversion, Voice Translation, QA scoring, deepfake risk detection, fraud detection and conditional recording. Call Center AI became free to try in September. Release 2.83.4 on October 26 adds a Conference mode beta for Voice Translation and makes Accent Conversion sound more natural at lower CPU cost, though the source note is truncated.

◆ Where it's heading

Two tracks are running side by side: security features (deepfake risk, in-call fraud detection) and the core voice tools getting wider coverage and lower cost to run. Conference mode takes Voice Translation beyond one-to-one agent calls into multi-party calls. Krisp is widening where its voice layer can run, not only what it detects.

◆ Prediction

Expect Conference mode and Fraud Detection to leave beta in an upcoming desktop release. The truncated note leaves the rest of 2.83.4 unclear.

O0.0

OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.

◆ Current state

OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.

◆ Where it's heading

The core bet is an AI-handles-first-contact, humans-handle-edge-cases pattern. Each Sona release is closing a deployment-blocker (instructions, transfers, free trial), while the call-flow tooling underneath is getting more flexible so AI and human routing can coexist in one config. Plan-tier expansion (call hold on Starter) suggests OpenPhone is also chasing volume in the lower segment.

◆ Prediction

Expect Sona to gain CRM-aware context (caller history, deal state) and outbound use cases — proactive callbacks, scheduled follow-ups. Pricing for Sona usage is likely to evolve from a flat add-on toward usage- or outcome-based once volume appears.
