Voice messages, by nature, prevent users from gauging the emotional tone without fully diving into the audio content. This hinders the shared emotional experience at the pre-retrieval stage. Research scarcely explored "Emotional Teasers"-pre-retrieval cues offering a glimpse into an awaiting message's emotional tone without disclosing its content. We introduce EmoWear, a smartwatch voice messaging system enabling users to apply 30 animation teasers on message bubbles to reflect emotions. EmoWear eases senders' choice by prioritizing emotions based on semantic and acoustic processing. EmoWear was evaluated in comparison with a mirroring system using color-coded message bubbles as emotional cues (N=24). Results showed EmoWear significantly enhanced emotional communication experience in both receiving and sending messages. The animated teasers were considered intuitive and valued for diverse expressions. Desirable interaction qualities and practical implications are distilled for future design. We thereby contribute both a novel system and empirical knowledge concerning emotional teasers for voice messaging.

EmoWear是一款智能手表语音消息系统，通过在消息气泡上应用30个动画提示，反映出情绪，进而提升语音消息中的情感交流体验。该系统通过语义和声学处理来优化情绪选择，研究表明EmoWear显著增强了接收和发送消息的情感交流体验，并被认为具有直观的丰富表达方式。研究对未来设计提出了有价值的交互质量和实际应用意见。
