Which one should you pick?
Pick OpenAI Whisper API if
You’re building around developers wanting raw transcription. Raw Whisper through OpenAI is still one of the cheapest ways to get high-quality transcription — $0.006/min for Whisper or gpt-4o-transcribe, and $0.
Pick SpeechRecognition (Python) if
You’re building around hobbyists and prototype builders who want one python import for many backends.. The SpeechRecognition library is a thin Python wrapper around Google Web Speech, Sphinx, AssemblyAI, Whisper, and more. The easiest way to slap voice input on a script.
