What is Krisp?
Every release now serves the contact center: translation, accent, fraud, analytics.
Krisp ships everything under one banner - Call Center AI - and all ten recent releases extend it. Four feature lines are in play: Voice Translation, Accent Conversion, Voice Security (deepfake detection and agent voice verification), and Speech Analytics. The most recent work has shifted from launching those lines to giving admins control over them: translated speech speed, Spell behavior, language management, access and audit controls. Cadence is steady, alternating desktop app builds (2.78 through 2.80) with roughly biweekly web update digests.
What is Telnyx?
Telnyx pulls the whole agent stack onto its own platform — and cuts voice AI loose from the phone line
Telnyx is shipping on two tracks at once. The steady one is model plumbing: GPT-5.4-mini, Kimi K3 on Inference, then GLM-5.2 and two GPT-5.6 variants, each slotted into Voice AI Assistants at a different cost-versus-reasoning point. The consequential one is structural — Edge Compute launched an Agent Runtime with Functions, KV, Cloud Storage, and Inference all GA, and Voice AI conversations now run over a direct WebSocket with no telephony involved. An Email API also entered beta, adding another channel to the same bill.

◆ Current state
Krisp ships everything under one banner - Call Center AI - and all ten recent releases extend it. Four feature lines are in play: Voice Translation, Accent Conversion, Voice Security (deepfake detection and agent voice verification), and Speech Analytics. The most recent work has shifted from launching those lines to giving admins control over them: translated speech speed, Spell behavior, language management, access and audit controls. Cadence is steady, alternating desktop app builds (2.78 through 2.80) with roughly biweekly web update digests.
◆ Where it's heading
The center of gravity is moving from agent-facing voice processing toward admin- and buyer-facing oversight. The Enterprise Analytics Portal and agent screen recording point at BPOs, whose own clients want visibility into the teams they contract. Accent Conversion has widened from the agent to both sides of the call, and Voice Security moved from launch into the paid trial. The repeating pattern across this window is: ship a line, then package it and instrument it.
◆ Prediction
Expect the next releases to keep filling in the administrative layer around Voice Security and Speech Analytics - retention windows, audit controls, and eventually the same externally-shareable portal treatment for security data that analytics just received.

Telnyx pulls the whole agent stack onto its own platform — and cuts voice AI loose from the phone line
◆ Current state
Telnyx is shipping on two tracks at once. The steady one is model plumbing: GPT-5.4-mini, Kimi K3 on Inference, then GLM-5.2 and two GPT-5.6 variants, each slotted into Voice AI Assistants at a different cost-versus-reasoning point. The consequential one is structural — Edge Compute launched an Agent Runtime with Functions, KV, Cloud Storage, and Inference all GA, and Voice AI conversations now run over a direct WebSocket with no telephony involved. An Email API also entered beta, adding another channel to the same bill.
◆ Where it's heading
The company built its position on owning telephony infrastructure, and it is now spending that position rather than defending it. Letting assistants stream PCM16 audio straight from a web or mobile client means the voice product no longer requires a phone number, which opens it to developers who were never going to buy carrier services. Edge Compute is the other half: instead of renting Telnyx a channel and hosting the agent elsewhere, the agent's compute, state, and storage sit next to the media path. Channel breadth — SMS, voice, WhatsApp, now email — is being levelled under one API and one invoice.
◆ Prediction
Expect StatefulActor and CloudFS to reach GA next, and the Email API to leave beta and get folded into the same unified billing pitch. The model-add cadence should continue at roughly its current pace as new releases appear.
