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 Synapse?
Synapse alternates release candidates with security patches on a tight two-week cycle
The feed is a straight release stream on a roughly two-week rhythm: a release candidate, a final, then point releases as needed. Recent substance sits in 1.157.0 — limits on scheduled delayed events, backward movement of fully read markers, time filters on the user-redaction admin API, and a configuration option to stop presence routing between users who merely share a room. 1.157.2 followed as a security release covering eleven advisories, six of them high severity.

Krisp
6.3COMMS
Every release now serves the contact center: translation, accent, fraud, analytics.
◆ 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.
Synapse
5.0COMMS
Synapse alternates release candidates with security patches on a tight two-week cycle
◆ Current state
The feed is a straight release stream on a roughly two-week rhythm: a release candidate, a final, then point releases as needed. Recent substance sits in 1.157.0 — limits on scheduled delayed events, backward movement of fully read markers, time filters on the user-redaction admin API, and a configuration option to stop presence routing between users who merely share a room. 1.157.2 followed as a security release covering eleven advisories, six of them high severity.
◆ Where it's heading
Development is tracking the Matrix specification process rather than a product roadmap of its own — most features arrive as implementations of numbered MSCs, several contributed from outside. The operational theme underneath is load and blast radius: presence exclusion, caps on delayed events, and locked sliding-sync connections all reduce what a busy homeserver has to carry. Security handling is centralized and batched, shipped as one patch release rather than trickled out.
◆ Prediction
Expect 1.159.0 to follow its release candidate within roughly a week, continuing the MSC-implementation pattern. The recent removal of deprecated auth delegation suggests more cleanup of experimental configuration in the coming releases.
