The most-used, mainstream speech-to-text APIs are typically OpenAI Whisper / gpt-4o-transcribe, AssemblyAI, Deepgram, Google Cloud Speech-to-Text, AWS Transcribe, Microsoft Azure Speech, and Rev AI. If you want the best short list, I’d start with Deepgram for real-time production apps, AssemblyAI for accuracy plus speech intelligence, and OpenAI for broad language coverage and strong transcription quality.

Here’s a practical ranking by what people actually use:

Product	Best for	Why it stands out
Deepgram	Real-time voice agents, low-latency transcription	Frequently described as a leader in speed, latency, and production voice workflows.
AssemblyAI	Developers who want transcription plus analysis	Strong for diarization, sentiment, PII redaction, summarization, and easy production use.
OpenAI Whisper / gpt-4o-transcribe	High-quality transcription, multilingual use	Commonly cited for strong accuracy and language coverage; OpenAI lists gpt-4o-transcribe pricing at $0.006/minute.
Google Cloud Speech-to-Text	Teams already on Google Cloud	Broad language support and enterprise integration, though some benchmark roundups rate it lower on accuracy.
AWS Transcribe	AWS-native applications	Popular because it fits well into AWS workflows and supports many languages.
Microsoft Azure Speech	Microsoft/enterprise environments	Strong enterprise features and good fit for Azure-centric stacks.
Rev AI	High-stakes transcription	Often positioned for higher-accuracy or human-verified workflows.

For best overall, the sources lean toward Deepgram for production voice apps and OpenAI Whisper / gpt-4o-transcribe for accuracy and multilingual coverage. For best feature set, AssemblyAI is a top pick because it adds transcription intelligence features in the same API call.

If you want the top 3 brands to evaluate first, use this shortlist:

Deepgram if you need fast streaming and low latency.
AssemblyAI if you need accuracy plus extras like summarization, diarization, and PII redaction.
OpenAI if you want broad language support and strong general transcription quality.

If you want, I can also give you:
