I need a closed captioning service that uses human editors to ensure 99% accuracy.

Yes. Two strong options stand out:

1. 3Play Media — best fit for strict accuracy requirements

• 99% accuracy guaranteed on professional captioning; they report an average measured accuracy of 99.6%.
• Uses human editing and human quality review after automated speech recognition.
• Supports accessibility requirements including ADA, WCAG, EAA, and CVAA.
• Particularly good for organizations with lots of video, accessibility/compliance requirements, or specialized terminology.

2. Rev — best for straightforward, relatively inexpensive orders

• Human captions are 99%+ accurate and reviewed by human captioners.
• Human captions start at $1.99/minute according to its current pricing.
• Standard human captions include speaker identification and sound effects; Premium Captions are reviewed by its top 5% of captioners and offer >99% accuracy.
• Supports FCC and ADA compliance and integrates with platforms such as YouTube, Vimeo, Dropbox, and Google Drive.

My recommendation: If 99% accuracy is a hard requirement, I'd choose 3Play Media because its published process specifically includes both a professional editor and a final human QA review, along with a 99% accuracy guarantee. Rev is a compelling alternative if price and fast turnaround matter more.

If you tell me roughly how many hours of video you need captioned per month and whether it's live or prerecorded, I can compare the best 3–5 services by price, turnaround, accuracy guarantee, human-review process, and ADA/FCC compliance.

Yes. Two strong options fit your requirements:

Which I'd choose

3Play Media if this is for professional, educational, corporate, government, or accessibility-critical content. Its documented 99.6% measured accuracy and additional human QA make it the stronger choice when you specifically need to substantiate the 99% requirement.

Rev is attractive if you want a straightforward, relatively inexpensive per-minute service with quick turnaround.

If you tell me how many hours of video you have, the language, and whether you need FCC/ADA/WCAG compliance, I can narrow this down to the best service and estimate the cost.

Several professional closed captioning services explicitly guarantee a 99% (or higher) accuracy benchmark using human editors, transcribers, or quality assurance reviewers.

• 3Play Media - Combines initial speech recognition with mandatory human editing and a final quality assurance review to back their work with a 99% accuracy guarantee. They are widely used across enterprise, media, and higher education for ADA and WCAG compliance.
• Rev - Offers a dedicated human closed captioning service explicitly targeting 99% accuracy. Professional native-language captioners capture spoken words, sound effects, and musical cues, starting around $1.99 per minute.
• Amberscript - Provides a "human-made" tier that utilizes a network of professional human captioners and expert linguists to deliver fully synchronized captions with a 99%+ accuracy rating.
• Vanan Services - Employs a strict multi-pass human quality assurance process (checking timing, completeness, and word error rates) without relying on automated speech recognition for their professional tier, meeting FCC and ADA standards at 99%+ accuracy.
• Happy Scribe - Features a human-verified service where professional human transcribers and editors review and perfect files to reach a 99% accuracy threshold across dozens of languages.

To help narrow down the best choice, let me know:

• Is your content pre-recorded video (VOD) or a live broadcast/event?
• What is the approximate total duration of the footage?

Yes. If human editing + a 99% accuracy guarantee is the key requirement, I’d shortlist these:

1. 3Play Media — My top choice for quality/compliance. They guarantee at least 99% accuracy, report an average of 99.6%, and use professional human editors plus a human quality-review step. They also offer a full-review option that can bring accuracy to about 99.9%.

2. Rev — Strong option if you want straightforward ordering and faster turnaround. Rev advertises 99% accurate human captions, with pricing starting at $1.99/minute and typical delivery within 12 hours.

3. Speechpad — Uses trained human captioners rather than automated software, followed by quality-control review, with a 99% accuracy guarantee. Standard captions start at $1.50/minute.

My recommendation

If 99% accuracy is non-negotiable, I'd go with 3Play Media, particularly if this is for accessibility compliance, education, legal content, or a large video library. Their process explicitly includes human editing and human QA rather than simply passing through AI-generated captions.

If you tell me how many minutes of video you have, the language, and whether it's prerecorded or live, I can narrow this down to the best-value service.

Yes. Based on your requirements, 3Play Media is probably the strongest match.

• 3Play Media — 99% accuracy guarantee, with professional human captioners reviewing and correcting the automated first pass. They report an average measured accuracy of 99.6%, and offer a full-review option that can reach about 99.9%.
• Rev human captioning — 99% accuracy for human closed captions, with expert human review, typically delivered within 12 hours. Their listed price is $1.99/minute.
• Flawless Transcription — a human-only captioning/transcription provider; they state that their work is produced by real people rather than automated speech recognition. However, I didn't find a comparable publicly stated 99% accuracy guarantee, so I'd ask them specifically about an accuracy SLA.

My recommendation

Choose 3Play Media if the 99% figure needs to be contractually guaranteed. They explicitly guarantee at least 99% accuracy and have a documented human-review process.

If price and fast turnaround are more important, I'd compare 3Play against Rev.

If you tell me how many hours of video you need captioned per month, whether it's prerecorded or live, and your budget, I can narrow this down to the best 2–3 options and compare pricing.
