Immigrants and foreigners in a country not their own
選ぶ前に確かめること
In the reviews, noise and the disappearance of access to a mode are what get in the way. What helps is a saved pair, a way to repeat a phrase and the option to read the recognized original.
Works as an overlay translator directly over WhatsApp and Instagram without switching apps. Built-in grammar check with multiple suggestions. Word list and personal dictionary mode. Weak spots: long messages get cut off, no full-screen support on iPad.
評価点：Overlay mode: translate text in any app without copying or leaving. Multiple translation engines in a single interface.
不満点：Long texts do not display in full. Grammar check does not show a correction when there is only one error.
向いている人：Users who message in social apps in a foreign language and want to translate right inside the chat without switching apps.
A key tool in the category. Free, compact (around 20 MB), and no subscription required. Supports group conversations via QR code. Recent updates have hurt voice mode stability.
評価点：Group conversation mode: multiple participants join via QR code and each see the translation in their own language in real time. Free with no usage limits.
不満点：After recent updates, voice recognition started mixing up languages and dropping words. There is a 1,000-character cap on text input, and the app does not tell you until you hit it.
向いている人：Anyone who needs a reliable free translator without subscriptions, especially for group meetings or business travel where translation into multiple languages is needed at once.
A specialized app for live two-way speech translation. Niche, but with a loyal audience. Main issue: voice stops working at the slightest background noise or pause.
評価点：Two-way conversation mode enables a real dialogue: each person speaks into the phone, the app auto-detects the language, and reads the translation aloud. Users praise accuracy on supported languages.
不満点：Voice recognition cuts out on any pause longer than half a second and requires louder, slower speech than natural conversation. In the free version, ads interrupt translation in the middle of someone speaking.
向いている人：People who need a tool for a live face-to-face conversation with someone in a foreign language and are willing to hold the phone between them and take turns speaking.
Voice translation works for live communication: users report using it on the job to understand Spanish-speaking coworkers. Camera is unreliable and sometimes produces nonsensical output. Japanese is inaccurate according to native speakers. Language flags are sometimes wrong (Tagalog shows the East Timor flag).
評価点：Voice mode with real recognition that is accurate enough for a working conversation in Spanish.
不満点：Camera translation is unstable. Accuracy for Japanese and several Asian languages is low according to native speakers.
向いている人：People relocating to or working in a Spanish-speaking environment who need a quick voice bridge.
A full-featured translator with text, voice, and a keyboard extension. Covers over 100 languages. Relevant for the category.
評価点：The built-in keyboard lets you translate right inside WhatsApp and other messengers without switching apps. Listening to pronunciation helps you both understand and reproduce a word.
不満点：Translation quality is inconsistent across languages: Italian works better than French, and Greek transliteration contains errors. Voice translation occasionally produces wrong phrases without any warning.
向いている人：Travelers and people who regularly message with foreign contacts and want to translate without leaving the chat.
