What is Deepgram?

Deepgram is widening language coverage while quietly replacing its diarization core.

Deepgram shipped a new batch speaker diarization architecture as an opt-in diarize_model parameter, then made it the default in the May self-hosted release. Alongside it, profanity filtering rolled out to 50+ monolingual languages and then to all multilingual models, numerals support reached Russian, Romanian, and Hebrew, and Gemini 3.1 Flash Lite replaced its preview version in the Voice Agent API.

What is Signal Desktop?

Signal Desktop's 8.35 beta returns to fix-only notes after contact sharing.

Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.35.0-beta.1 is another of those, following v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling, and v8.32.0-beta.1, which extended the unread filter into folders and search.

Deepgram vs Signal Desktop: editorial side-by-side

D0.0

Deepgram is widening language coverage while quietly replacing its diarization core.

◆ Current state

Deepgram shipped a new batch speaker diarization architecture as an opt-in diarize_model parameter, then made it the default in the May self-hosted release. Alongside it, profanity filtering rolled out to 50+ monolingual languages and then to all multilingual models, numerals support reached Russian, Romanian, and Hebrew, and Gemini 3.1 Flash Lite replaced its preview version in the Voice Agent API.

◆ Where it's heading

Two tracks run at once. The model track is a genuine architecture replacement in diarization, moved from opt-in to default inside a week and a half, which is a fast promotion for a core speech component. The coverage track is unglamorous breadth — languages, filters, numerals — that determines whether the platform can be adopted outside English-first markets. The Voice Agent work is managed-model plumbing rather than a direction of its own.

◆ Prediction

Diarization v2 should reach streaming after landing in batch and self-hosted, since that is where the earlier architecture is weakest for live agents. Expect the language-coverage releases to continue at the same steady cadence.

S5.0

Signal Desktop's 8.35 beta returns to fix-only notes after contact sharing.

◆ Current state

Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.35.0-beta.1 is another of those, following v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling, and v8.32.0-beta.1, which extended the unread filter into folders and search.

◆ Where it's heading

The desktop app is closing gaps with mobile one feature at a time, separated by maintenance betas. Visible features arrive about every two to three builds.

◆ Prediction

The next feature beta is likely within one or two builds, based on the cadence since October. The entries don't indicate what it will contain.
