## 5 Discussion  
### Implication  
(1) Provide an impromptu mobile music culture space. Music sharing is now changing from an environment where providers are determined to an environment where users can create and consume freely. In this paper, the proposed karaoke system enables users to recreate their own songs regardless of when and where they are and share them with other users' intermanously. While most of the various music services surveyed in previous studies forced passive listening, the proposed karaoke system presents an important possibility for the creation of more active digital cultural spaces and changing mobile life by giving users a re-creation function. The model encourages healthy interaction and engagement for users without the need for extensive planning. It is user-friendly, it responds quickly, and it creates music for users together. (2) Provide convenient touch and voice UI for mobile users. The voice and touch UI is useful even in situations where users are engaged in tasks, including driving or other activities. Most modern song services focus on listening to streaming services, but a more convenient interface in addition to touch is important to listen to and to sing along to in mobile environments. In the proposed karaoke service, voice recognition and TTS functions are provided based on a predetermined voice set and state to enable system control based on voice. Therefore, users are able not only to see and touch the screen but also to utilize voice commands to control music sharing while moving or driving. The design of the touch interface with its simplicity and intuitiveness provides recognizable icons, buttons, and

navigation panels for users. Users can easily initiate activities with voice and touch UI commands and can tune into music according to their interests. (3) Improve performance and management through distributed processing. The configuration of services through collaboration between the cloud server and the user's smartphone is effective. When sharing music between users, the method of sharing music with nearby users has the disadvantage of increasing the network load of smartphone users. In the karaoke system, the cloud server manages the group and performs voice streaming to minimize the impact on the performance of music transmission and reception even when the number of users increases. The cloud server receives UPD data packets from a smartphone user and then copies and delivers them to other smartphones continuously, thus being independent of the number and performance of mobile devices. Parallel processing breaks down complex tasks into smaller segments and processes multiple nodes simultaneously. Because of that, overall execution time is reduced, and the tasks are completed in a short time. (4) Impact of digital cultural spaces and users' mobile lives. There are several ways by which the proposed karaoke system has an impact on digital cultural spaces and users' mobile lives in a positive way. It acts as a significant platform for cultural expression and interaction. With this system, users can sing a song in their native culture and language that forecasts the diversity of cultural spaces. In this technology, people are connected to each other in the group, so, online community centers can be formed to share similar interests among music enthusiasts. These communities can serve as core aspects of users' mobile lives that offer a sense of membership and affiliation. It is also an entertaining and stress-relieving tool to have fun in daily life using smartphones. Moreover, the karaoke system provides a digital platform to share songs that promote user-generated content and culture. To improve their singing skills, users can rehearse using this system and gain valuable knowledge. In simple words, this system is a form of informal education integrated into users' mobile lives. It can also be utilized in the form of entrepreneurial opportunities.
