Assignee: AIROHA TECHNOLOGY CORP.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 5:
6. A method for enhancing speech sound quality, applied in a first wireless earbud and a second wireless earbud, wherein the first wireless earbud comprises a first speaker and a first downlink speech process path coupled to the first speaker, the first downlink speech process path comprises a first packet loss concealment (PLC) processor and an inverter, the second wireless earbud comprises a second speaker and a second downlink speech process path coupled to the second speaker, the second downlink speech process path comprises a second PLC processor, the method comprising:
receiving, by the first PLC processor, a first mono speech stream corresponding to mono speech data transmitted from a mobile phone;
performing, by the first PLC processor, a first algorithm for reducing effects of packet loss on the first mono speech data to generate a first compensated data;
generating, by the inverter, an inverted speech data or an inverted speech signal based on the first compensated data generated by the first PLC processor;
playing, by the first speaker, a first analog signal corresponding to the inverted speech data, or the inverted speech signal;
receiving, by the second PLC processor, a second mono speech stream corresponding to the mono speech data transmitted from the mobile phone;
performing, by the second PLC processor, the first algorithm for reducing effects of packet loss on the second mono speech data to generate a second compensated data; and
playing, by the second speaker, a second analog signal corresponding to the second compensated data.
