To measure the accuracy of Microsoft's speech-to-text accuracy when processing your audio files, you must provide human-labeled transcriptions (word-by-word) for comparison. While human-labeled transcription is often time consuming, it's necessary to evaluate accuracy and to train the model for your use cases. Keep in mind, the improvements in recognition will only be as good as the data provided. For that reason, it's important that only high-quality transcripts are uploaded.
