![]() ![]() ![]() Ground truth is the 100% accurate transcription, typically human-provided, that you use to compare and measure accuracy. You might also see the term, ground truth, used in the context of ASR accuracy. ![]() A lower WER means that the system is more accurate. WER measures the percentage of incorrect word transcriptions in the entire set. However, the industry standard method for comparison is Word Error Rate (WER), often abbreviated as WER. It might be useful for you to use multiple metrics, depending on your needs. Speech accuracy can be measured in a variety of ways. We offer a wide variety of models tailored for different use cases, such as long-form audio, medical or over-the-phone conversations. In Google's Cloud Speech-to-Text API, accuracy tuning can be done by choosing the most appropriate recognition model and by using our Speech Adaptation API. Once you measure your accuracy, it's possible to tune the systems to provide even greater accuracy for your specific situation. If you plan to rely on ASR for critical systems, it's very important to measure its accuracy or overall quality to understand how it performs in your broader system that integrates it. However, machine learning systems are rarely 100% accurate, and ASR is no exception. ASR has many applications from subtitling, to virtual assistants, to Interactive Voice Responses (IVRs), to dictation, and more.
