VoiceAssist: Guiding Users to High-Quality Voice Recordings

Voice recording is a challenging task with many pitfalls due to sub-par recording environments, mistakes in recording setup, microphone quality, etc. Newcomers to voice recording often have difficulty recording their voice, leading to recordings with low sound quality. Many amateur recordings of poor quality have two key problems: too much reverberation (echo), and too much background noise (e.g. fans, electronics, street noise). We present VoiceAssist, a system that helps inexperienced users produce high quality recordings by providing real-time visual feedback on audio quality. We integrate modern audio quality measures into an interactive human-machine feedback loop, so that the audio quality can be maximized at capture-time. We demonstrate the utility of this feedback for improving the recording quality with a user study. When presented with visual feedback about recording quality, users produced recordings that were strongly preferred by third-party listeners, when compared to recordings made without this feedback.
