Speech-to-Text SLAs: Uptime, Latency Targets, and What Breaks First

Uptime badges hide concurrency cliffs and regional latency. I've mapped what speech-to-text SLAs really cover and what to load-test before you sign a vendor contract.

Your Deepgram Voice Agent Pilot Just Got 34% More Expensive: Unbundle STT Before Sept 13

Deepgram's Voice Agent promo ends Sept 12 — Standard jumps 34% on Sept 13. I've mapped the tier math and three migration paths, including unbundling STT with Pipecat.

Speech-to-Text for Knowledge Base Ingestion: From Calls to Searchable Docs

I've wired call recordings into searchable knowledge bases for four B2B teams. This guide covers the ingest pipeline: preprocessing, Agent-mode transcription, metadata, dedupe, and chunk tuning for RAG-ready content.

Agent-Mode Transcription for RAG Pipelines: Fewer Tokens, Cleaner Chunks

Agent-mode transcription for RAG pipelines shrinks filler before chunking. I've measured 35-50% fewer tokens vs Raw, cleaner retrieval, and lower embed cost.

Speech-to-Text for Incident Response Recordings: Chain of Custody Without Public APIs

I've sat on IR bridges where war-room audio got dropped into a public Whisper API for searchable notes. That habit breaks chain of custody. Here's the private transcription pattern I use when recordings may become evidence.

Zero-Retention Transcription APIs: What 'No Training' Actually Guarantees

No training is not zero retention. I break down OpenAI, Deepgram, and AssemblyAI retention defaults, then the DPA language and retrieve-after-N-minutes test I require before production audio leaves the VPC.

Transcription Confidence Scores: When to Trust Them (and When to Ignore Them)

I've watched production teams treat transcription confidence scores like a truth meter. Here's what those numbers measure, when to trust them, and how agents should fall back.
