Comparison
Compare speech-to-text APIs: PyAI Hear vs Deepgram and AssemblyAI
PyAI Hear provides eight-language sync and streaming STT on an OpenAI-compatible endpoint, with a first partial measured around 200 ms in-region. Deepgram publishes faster interim latency and supports more languages. We don't grade our own accuracy. That lives on Artificial Analysis.

Methodology: prices are the cost to transcribe 1,000 minutes of audio. PyAI Hear is $0.001/min streaming ($1.00) and $0.0005/min batch ($0.5). Competitor prices are Artificial Analysis’s normalized estimates (which fold in different billing models) as of June 2026; providers change pricing often, so confirm with each before deciding. Accuracy (WER) and speed are independent - see the linked leaderboard.
