Timekettle W4 AI 인터프리터 이어버드

Language barriers made communication difficult at international conferences or while traveling. Phone app translators had to be held up alternately to the other person, translator devices had to be carried separately, and the natural flow of conversation was interrupted.

In addition, voice recognition errors were frequent in real-world environments with ambient noise, hindering accurate translation.

The W4 earbuds allow translation to occur as if users are conversing, with each user wearing one earbud[85]. Equipped with an AI translation engine that supports 40+ languages and 93 accents, when one person speaks in their native language, it is delivered to the other person's ear in the desired language in near real-time[86].

In particular, the bone conduction microphone and three-microphone array clearly extract only the user's voice and eliminate ambient noise, increasing translation accuracy[87]. The translation delay is also reduced to several hundred milliseconds, providing an experience close to simultaneous interpretation.

In addition, offline mode enables translation of major languages without the internet, and situation-specific modes such as "Listening Mode" are provided, optimized for various scenarios such as conferences and listening to travel guides[88][89]. In summary, it is a device that acts as an interpreter simply by inserting it into your ear without a smartphone.

Individual consumers (B2C) such as overseas travelers, multicultural families, international students, and business travelers are the main customers.

There is also B2B demand for bulk purchases for educational/business purposes in schools and multinational corporations. For example, they can be placed at hotel front desks or public institution counters for use.

Timekettle already has a sales network worldwide, so the new W4 is also aimed at the global market.

As translation accuracy continues to improve, it can be further segmented into business-specific uses (medical/legal interpretation). Although it competes with the smartphone's own translation function, the convenience of the earbud form factor is expected to steadily create demand.

With evaluations such as "It actually works – a dream interpreter," the W4 is receiving reviews as the best translation earbud with improved performance over the previous generation[90]. It was also praised at CES as an "experience that breaks down language barriers"[85], and its noise cancellation performance and minor usability features (subtitle mode, etc.) are mentioned as strengths.

However, there are still limitations to perfect translation, so it is also suggested that it is only supplementary for formal business translation purposes. Nevertheless, it is a leader in the industry in terms of portability and real-time performance, and the market outlook is positive.
