Enhanced Voice Post Processing Using Voice Decoder Guidance Indicators
This is an incremental improvement for voice communication systems.
The paper tackled the problem of independent voice enhancement and coding in communication systems by proposing to use voice decoding information to improve downlink voice enhancement, resulting in improved quality.
Voice enhancement and voice coding are imperative and important functions in a voice-communication system. However, both functions are commonly treated independently, even though both utilize similar features of the underlying signals. Our proposal is to leverage information from one function to the benefit of the other. Specifically, our proposed changes are focused on changes to the voice enhancement at the downlink side and utilizing information of the voice decoding. Preliminary results show that such an approach results in improved quality. Additionally, suggestions are provided on future extensions of the proposed concept.
