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.
Voice Activity Detection Before Transcription: Cut Silence, Cost, and Latency
I've deployed VAD in production transcription pipelines. Here's how to cut silence before STT and lower cost and latency without hurting transcript accuracy.
Webhook Signature Verification for Transcription APIs: Stop Spoofed Callbacks
Spoofed transcription webhooks can flood your agent queue with fake completions. Here's the HMAC verification pattern I use on every async STT deployment.
Streaming Speech-to-Text over WebSockets: Latency Budgets That Actually Matter
Streaming speech-to-text over WebSockets only works when you budget first partial, final commit, and reconnect. I share the targets I use for live AI agents.
Python Speech-to-Text API: Transcribe Audio Files with Privocio
Learn how to use a Python speech-to-text API to transcribe audio files with httpx, Bearer authentication, Whisper-compatible models, and Privocio's private STT infrastructure.
Audio Preprocessing for Transcription: FFmpeg Settings That Improve Accuracy
Audio preprocessing for transcription beats prompt tuning. I share the FFmpeg commands I run before every STT upload: mono 16 kHz, highpass, loudnorm, and when not to denoise.
Build a LangChain Voice Agent with Privocio Speech-to-Text
Wire Privocio speech-to-text into a LangChain agent: STT with the OpenAI Python client, Agent output mode for token savings, and an end-to-end voice-to-LLM example.
Speech-to-Text API Error Handling: Retries, Timeouts, and Fallback Patterns
I've debugged STT pipelines that fail at 2am. Here's the retry, timeout, and fallback pattern I use for speech-to-text API error handling in production.
Migrating Off OpenAI Realtime API: A Developer's Guide to Private, Flat-Rate Streaming STT
I've migrated 4 voice agents off OpenAI Realtime API. Here's the SDK swap, 400+ hr/month cost math, and which migration path to pick.
Speech-to-Text for AI Agents: How to Build Voice-Enabled Agent Pipelines
I've built voice-enabled AI agent pipelines for production workloads — here's the complete guide to choosing and integrating speech-to-text.
