An in-depth assessment of ASR engines by one of our key clients showed that Speechmatics has the most accurate speech recognition engine on the market. The company assessed the word error rate (WER) of 11 speech providers on a 400min audio test that contained mixed content from religion, finance, contact centres, conference calls and webinars; all at different qualities (high, low, background noise etc.) and sample rates (8-16 kHz and mixed). The top three are:

  1. Speechmatics – 33% WER

  2. S****** - 43% WER

  3. V****** - 49% WER.
