ViSQOL v3: An Open Source Production Ready Objective Speech and Audio Metric
This provides a production-ready tool for audio quality assessment, but it is incremental as it builds on existing versions.
The authors released ViSQOL v3, an open-source objective metric for speech and audio quality, improving upon previous versions in design and usage, and benchmarked it against real-world data for evaluation.
Estimation of perceptual quality in audio and speech is possible using a variety of methods. The combined v3 release of ViSQOL and ViSQOLAudio (for speech and audio, respectively,) provides improvements upon previous versions, in terms of both design and usage. As an open source C++ library or binary with permissive licensing, ViSQOL can now be deployed beyond the research context into production usage. The feedback from internal production teams at Google has helped to improve this new release, and serves to show cases where it is most applicable, as well as to highlight limitations. The new model is benchmarked against real-world data for evaluation purposes. The trends and direction of future work is discussed.
