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.
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.
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.
Speech-to-Text API with cURL: Transcribe Audio from the Command Line
Transcribe audio with cURL and Privocio's speech-to-text API. Batch uploads, OpenAI-compatible routes, and SSE streaming from your terminal or CI pipeline.
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.
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.
Go Speech-to-Text API: Transcribe Audio with the OpenAI Go SDK
Transcribe audio in Go using the OpenAI Go client with a Privocio base URL. Whisper-compatible batch transcription for backend services and AI agents.
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 API Rate Limits: Concurrency, Quotas, and What Breaks at Scale
Rate limits kill speech-to-text pipelines before cost or accuracy ever matter. I've stress-tested six providers under load and mapped what breaks at scale.
Speech-to-Text for Mobile Apps: On-Device vs API Transcription Compared
I've shipped voice into six mobile apps. Here's when on-device Whisper beats a cloud API — and when fixed-rate private transcription wins on battery, privacy, and cost.
Batch Transcription API Best Practices: Preprocessing, Retries, and Cost Control
I've debugged batch STT pipelines that failed 40% of files. Here's the FFmpeg preprocessing, retry logic, and cost controls I use in production.
