SayMi

SayMi — also known as EarJoy (Android package: com.watchfun.classearjoy) — is a free companion app for AI translation earbuds developed by Shenzhen Watch Fun Internet Technology Co., Ltd. Once you pair compatible Bluetooth earbuds with the SayMi app, it enables real-time voice translation in 100+ languages. The app offers two main translation modes: Headphones+Phone Mode (you wear the earbuds and hear translations while others speak into your phone) and Free Talk Mode (both speakers each wear one earbud for natural back-and-forth conversation). Beyond translation, SayMi also manages earbuds settings, monitors battery levels, and includes a sleep relaxation music library. It is free to download on Google Play (1M+ downloads, 4.1 stars) and the Apple App Store (3.4 stars).

SayMi uses cloud-based AI translation to convert spoken speech to text, translate it, and then convert the translated text back to speech — all in near real-time. Here's how the process works: (1) Voice capture: SayMi uses your phone's microphone (or the earbuds' mic) to capture the speaker's voice. (2) Speech-to-text: the audio is processed by AI to convert speech into text. (3) Translation: the recognized text is translated into the target language using AI translation models. (4) Text-to-speech: the translated text is converted back to audio and delivered through your earbuds. The entire cycle happens in seconds, enabling natural conversation. Translation accuracy is highest for clearly spoken, standard speech in major languages. Noisy environments, strong accents, or very fast speech may reduce accuracy.

SayMi claims to support 100+ languages for translation. Core supported languages include English, Spanish, French, German, Portuguese, Italian, Russian, Japanese, Korean, Chinese (Simplified and Traditional), Thai, Vietnamese, Indonesian, Malay, Arabic, Hindi, and many more. The app's interface itself is available in 16 languages: Arabic, English, French, German, Indonesian, Italian, Japanese, Korean, Malay, Portuguese, Russian, Chinese Simplified, Spanish, Thai, Chinese Traditional, and Vietnamese. Language coverage is strongest for major world languages. Some less common languages or regional dialects may have lower translation accuracy. New languages are added with app updates.

To connect your earbuds to the SayMi app: (1) Install SayMi from Google Play or the Apple App Store. (2) Enable Bluetooth on your phone. (3) Put your AI translation earbuds into pairing mode — typically by holding the button on the case or earbuds until the LED flashes. (4) Open the SayMi app and tap the device/earbuds icon on the home screen. (5) Select your earbuds from the list of available Bluetooth devices. (6) Confirm the pairing when prompted. Once connected, a green indicator or battery display confirms the connection. If your earbuds don't appear in the list, ensure they are in pairing mode and within Bluetooth range (within ~10 meters). Make sure SayMi has Bluetooth and microphone permissions in your phone settings.

Common issues and fixes for SayMi: (1) Earbuds not pairing — ensure the earbuds are in pairing mode (check your earbud manual). Forget the device in your phone's Bluetooth settings and try re-pairing from within the app. (2) Translation audio plays through phone speaker instead of earbuds — this is a known issue. Try closing and reopening the app, and ensure your earbuds are the active audio output device. Check phone audio settings to set earbuds as the default audio device. (3) App crashes on startup — clear the SayMi app cache (Android: Settings > Apps > SayMi > Storage > Clear Cache), then restart. Or uninstall and reinstall. (4) Poor translation accuracy — move to a quieter environment, speak slowly and clearly, and ensure the microphone is not blocked. (5) Connection drops — keep your phone within 10 meters of the earbuds, and ensure SayMi has background activity permissions to prevent the OS from killing the app.

Yes — SayMi is completely free to download and use on both Android and iOS. There are no in-app purchases, subscriptions, or premium tiers. All core features — dual-ear translation, 100+ languages, Bluetooth headset management, AI chart, sleep music — are available at no cost. The app's revenue model is tied to hardware sales: SayMi serves as the companion app for AI translation earbuds sold by affiliated brands. This means no hidden paywalls for the app itself.

SayMi (EarJoy) is designed for AI translation earbuds that ship with a QR code or instruction pointing to the SayMi app or the EarJoy app (package: com.watchfun.classearjoy). Compatible devices include: ClassEarJoy AI translation earbuds (the primary branded product), Mimiso AI translation earbuds, and various other unbranded AI translation earbuds sold on Amazon, AliExpress, and other online platforms that use the SayMi/EarJoy app as their companion. If your earbuds' packaging instructs you to download 'SayMi' or 'EarJoy' and the QR code leads to com.watchfun.classearjoy, these are the correct earbuds for this app. Standard Bluetooth headphones (like AirPods or Galaxy Buds) are not designed to use SayMi for AI translation — the translation feature requires the specific AI earbuds hardware.

SayMi offers two main translation modes: (1) Headphones+Phone Mode — You wear the earbuds. The other person speaks into your phone's microphone in their language. SayMi translates their speech and plays the translation through your earbuds. Best for: listening to and understanding a foreign-language speaker in real time. Setup: Open SayMi → tap 'Translation' → select 'Headphones+Phone Mode' → choose the speaker's language (source) and your language (target) → tap Start. (2) Free Talk Mode — Both you and the other person each wear one earbud from the same pair. You speak your language; they hear the translation through their earbud. They speak their language; you hear the translation through your earbud. Best for: natural back-and-forth conversations where both parties participate actively. Setup: Open SayMi → tap 'Translation' → select 'Free Talk Mode' → assign languages to each person → tap Start.

SayMi is developed by Shenzhen Watch Fun Internet Technology Co., Ltd., a Chinese technology company. On the App Store, SayMi declares it collects Audio data (used for translation processing). The privacy policy states that data is encrypted in transit, and users can request data deletion by contacting the developer. The app requires microphone access (required for voice translation) and Bluetooth permissions. As with any cloud-based translation app that processes voice audio, your spoken words are transmitted to servers for translation. If data privacy is a concern, review the full privacy policy at https://classicearjoy.com/app-about-h5?code=privacy_policy before use. The app does not appear to collect financial, location, or contact data based on App Store disclosures.

SayMi and Google Translate serve different use cases: SayMi (EarJoy) is specifically designed for earbud-based face-to-face translation. Its key advantage is the Dual-Ear mode — both parties each wear one earbud and hear translations without touching the phone. This creates a more natural, immersive conversation experience. SayMi requires compatible AI translation earbuds. Google Translate offers a Conversation mode that works without earbuds — you hold the phone between you and a conversation partner. Google Translate supports more languages (100+) with better offline options (downloadable language packs). SayMi is better for: earbud-based hands-free conversations, travel situations where you want to keep the phone pocketed. Google Translate is better for: quick one-off translations, document/text translation, offline use, and situations where you don't have compatible earbuds.
