TwinMind is announcing a new breakthrough in AI speech technology and releasing the world's most accurate speech recognition model today.
The new TwinMind Ear–3 model achieved the industry's highest accuracy for speech to text, significantly outperforming the previous leading services from Eleven Labs, Deepgram, Assembly AI, and Speechmatics in head‑to‑head evaluations.
This is the first and only model with true global coverage supporting 140+ languages
TwinMind has set a new industry standard in each of the 4 categories:
Accuracy: 5.26% WER (Word Error Rate)
Speaker Diarization: 3.8% DER (Diarization Error Rate)
Languages: 140+ (over 40 more languages than what others provide)
Price: $0.23/hour (lowest cost among leading services)
Evaluating TwinMind alongside top speech-to-text providers across key performance metrics.
From the first word to the last, TwinMind delivers transcripts you can trust with accurate speaker tracking with precise time-stamps, rich audio-event details, and unprecedented multilingual support. Whether you have a meeting or ten thousand hours of archives in niche languages, TwinMind delivers the industry-standard performance.
A new gold standard for accuracy, cost, and languages
Breaking Barriers with 140+ Languages
Word Error Rate (WER) measures how often a transcription system makes mistakes by counting wrong words, missing words, and extra words that weren’t spoken.
TwinMind achieves the lowest WER at 5.26%, outperforming the previous best, Eleven Labs, by 12.47%.
Speaker Diarization Error Rate (DER) measures a system’s ability to determine “who spoke when,” factoring in missed speech, false alarms, and speaker mix-ups. TwinMind achieves a remarkable 3.8% DER, narrowly surpassing the previous leader, Speechmatics, at 3.9%.
This performance comes from a sophisticated processing pipeline that cleans and enhances audio before diarization, then applies precise alignment checks to refine the results. The outcome is consistently accurate speaker separation, even in challenging, noisy, or fast-paced conversations
(OpenAI Whisper is excluded from this chart as it does not offer speaker diarization).
At just $0.23 per hour, TwinMind delivers industry-leading accuracy despite having the lowest cost.
Compared to major providers, it’s 11.5% cheaper than Deepgram, 37.8% cheaper than Assembly AI, and 42.5% cheaper than Eleven Labs.
Optimized for long-form conversations, it tags speakers, handles code-switching, and generates precise timestamps and punctuated transcripts.
With it's unprecedented price point TwinMind makes enterprise-grade quality accessible at scale even for all day transcription use cases.
With support for over 140 languages, TwinMind is the first and only model with true global coverage in the industry. That’s 100 more languages compared to Otter and Deepgram, and over 40 more languages than OpenAI Whisper, Assembly AI, and Eleven Labs.
