Dịch giọng nói có cần cài ứng dụng không?

Không. Công cụ chạy trực tiếp trên trình duyệt. Bạn chỉ cần cấp quyền microphone khi muốn sử dụng nhận dạng giọng nói.

Tại sao đôi khi nhận dạng sai?

Độ chính xác phụ thuộc môi trường, micro, tốc độ nói, giọng địa phương và khả năng nhận dạng của trình duyệt. Vì vậy phần văn bản nhận dạng luôn có nút Sửa trước khi dịch lại.

Tôi có thể nghe bản dịch không?

Có. Khi có bản dịch, nút loa dùng speech synthesis của trình duyệt để đọc nội dung thành tiếng nếu thiết bị hỗ trợ.

Everyday use

When voice translation is useful

Use short, complete sentences and review important details before you act on a machine translation.

Travel and directions

Translate short questions at airports, stations, hotels, restaurants or when asking for directions.

Two-person conversations

Take turns speaking or typing while keeping the source sentence and translation visible in one session.

Prepare a sentence to say

Translate what you want to say, check the wording, then play the target-language voice when your device supports it.

Check before using

Make the result easier to trust

Speech recognition and machine translation are separate steps. A quick source-text review prevents many avoidable mistakes.

Review names and numbers

Check names, addresses, prices, dates and booking numbers in the recognized source before translating.

Prefer one idea per sentence

Short, complete sentences are easier to recognize and easier to verify than long speech with several ideas.

Type when the room is noisy

Microphone input is optional. Typing is often more reliable in crowds, traffic or places with loud background audio.

FAQ

Voice translation on the web

Quick answers about microphone input, text entry, speech playback and translation reliability.

Do I need to install an app?

No. The translator runs in the browser. Microphone input is optional and only works when your browser/device supports speech recognition.

Can I translate without a microphone?

Yes. Type or paste text into the source field and translate normally. This is also useful in noisy environments.

Why can speech recognition be wrong?

Accuracy depends on the microphone, background noise, pronunciation, speaking speed and the speech-recognition service available on your device.

Can I listen to the translation?

Yes when your browser or operating system provides a compatible text-to-speech voice for the target language.
