70/100
Seven-aspect task score

Cleanvoice AI includes 30 free signup minutes (no credit card) and its Summarize workflow generates speaker-labeled transcripts with native exports in 9 formats (.TXT, .SRT, .VTT, .TTML); it captures all 68 spoken words, though spaces around numeric punctuation and a ~280s async queue make it best suited for batch podcast post-production.

Word accuracy: 79.4% · Keyword recall: 60% · Verification token: Fail · Audio duration: 38.9s

Fixture findings

On the 38.86s English speech anchor, it captures all 68 words (79.4% word accuracy, 60.0% keyword recall), scoring 39.8/65 on strict string matching because punctuation formatting inserts spaces around numbers and hyphens (e.g., "$14 ,850 .50", "2026 -0814") and lemmatizes "Verified" to "Verify".

Original historical observation
