Core Viewpoint - The introduction of "Beidou Voice Message" service by China Telecom addresses the issue of unstable mobile signals in remote areas, providing a reliable communication method during emergencies [2][10]. Group 1: Technology Overview - "Beidou Voice Message" is not a traditional SMS or voice call; it utilizes China's Beidou satellite system and proprietary AI voice encoding algorithms to efficiently compress voice content into minimal data [3]. - The service employs a unique "voiceprint and semantic separation AI algorithm," which separates voiceprint features from semantic content for efficient transmission and restoration of voice messages [4]. - This technology can compress 20 Chinese characters into a 6-second voice message, eliminating the need for manual text input [5]. Group 2: Application and Benefits - In emergency situations, voice messages can convey emotions and surrounding sounds, enhancing communication efficiency compared to text messages [9]. - The service allows users to send voice location distress signals even in extreme environments without ground network signals, improving rescue efficiency [10]. - The service is particularly beneficial for outdoor adventurers, fishermen, and geological explorers, providing a critical communication tool in remote areas [11]. Group 3: Market Context and Future Developments - The launch of the Beidou Voice Message service is a significant enhancement to existing communication technologies, especially in areas with weak signal coverage [11]. - Huawei has introduced the first terminal device, WATCH Ultimate 2, supporting Beidou satellite voice messaging, enabling users to send 10-second voice messages in areas without mobile networks [12]. - Xiaomi's REDMI Note 15 Pro+ is set to upgrade to support Beidou "rich media communication," allowing the sending of images and voice messages, although it is limited to China Mobile networks [14]. - The industry is actively advancing satellite communication, with both mobile manufacturers and operators pushing for direct satellite connectivity for enhanced communication capabilities [17].
