Translation Modes
The Merryking app offers several translation modes to suit different communication needs:

Image: An illustration of "Touch Mode." A man is wearing an earbud, and the text describes this mode for fluent conversation. Each participant wears an earbud, and they touch the earbud before speaking, with translation heard within 0.5-3 seconds.
Image: An illustration of "Free Speech Mode." Two business professionals are engaged in conversation. The accompanying text explains that this mode is for in-depth one-on-one conversations, where each person wears an earbud and speaks normally without needing to touch the earbud, enabling hassle-free communication.
- Speaker Mode: Ideal for short interactions, such as asking for directions or ordering food. You wear one earbud and speak, and the translation is played aloud through your phone's speaker for the other person to hear.
- Touch Mode: For fluent two-way conversations. Each participant wears an earbud. Touch your earbud before speaking, and the translation will be delivered to the other person's earbud within 0.5-3 seconds.
- Free Speech Mode: Designed for in-depth, continuous conversations. Both participants wear an earbud and can speak naturally without needing to touch the earbuds. The system automatically detects and translates speech.
- Offline Mode: Allows translation without an internet connection for pre-downloaded language packs. (Requires in-app purchase for certain languages).
- Audio Transcription: Converts spoken language into text.
- Photo Translation: Translates text from images.
