Verdict — pick by your requirement
Multilingual + private/on-device: run a local Whisper model. It supports 100+ languages with no upload required. Diarization quality varies — test it with your own audio.
Meeting recording, want speaker labels + SRT fast: use HappyScribe / TurboScribe / VEED (paid, cloud). Check diarization results against a real call before relying on them.
Free quick try: use the TurboScribe free plan or a Whisper-based tool. Export format limits are common.
Chinese/long-form video:decopy.ai / TalkMapper appeared in SERP results with timestamp + speaker support — test the accuracy on your own material.
Evidence (SERP-observed, 2026-09-30)
"audio to text transcription" SERP: snipsound, audioscribe.io, happyscribe, soundtools — a crowded space with 5+ established SaaS products; independent head-to-head testing remains limited.
"video to text transcription": videotranscriber.ai, decopy.ai (2026-09-23), VEED, TurboScribe, any2text — product pages dominate results, with little editorial comparison available.
Prior audit (#1): TalkMapper, Rewind.ai, Free.ai, WhisperAI + 1–2 listicles. Signal: strong selection intent, but SERP is already crowded with vendors → a tougher target for a DR0 site than PDF-to-Excel.
