Frequently Asked Questions
We're here to help you.

Is the benchmark report free? Yes!

How is accuracy calculated? Word Error Rate (WER) is the industry standard for calculating the accuracy of an automatic speech recognition system. The WER compares the predicted transcription to a human transcription for an audio file, and counts the number of insertions, deletions, and substitutions made by the automatic speech recognition system in order to derive the WER. TLDR - we compare API transcripts with human transcripts to calculate Word Error Rate (WER).

Why should I get a benchmark report? Shopping for speech-to-text can be tricky. Every provider claims they have the "best" accuracy. Instead of promising, we'd like to show you first hand how well we perform. We provide all raw transcripts in case you'd like to run any additional internal benchmarking.
