Change the interface without changing your speech settings
Open Settings > Appearance & app > Display language. Choose an available interface language or follow your system language. The system-language option uses a supported system language and falls back to English when it cannot match.
This setting does not select a speech language or translate your dictation. The website’s language choices are separate again: the number of website translations is not a count of supported recognition languages.
Choose automatic detection or your usual languages
Open Settings > Voice & translation > Input languages. The app loads available languages from the current service. Choose Detect automatically if you want recognition without a manually selected language list, or select the languages you commonly speak.
Use automatic detection, or choose up to 4 of 30 recognition languages as preferences for your next recording. Pick only the ones you actually speak.
- Wait for the supported language choices to finish loading.
- Choose Detect automatically, or select only the relevant languages shown.
- If you have reached the displayed limit, deselect one before adding another.
- Check for a save error. Successfully saved changes apply to your next recording.
Set up an English or Chinese writing session
For an English passage, start with automatic detection or choose English when it is offered. Do the same for Chinese using the currently available choice. You can keep your preferred menu language throughout.
If a passage contains both Chinese and English, you may use automatic detection or relevant supported hints. Review names, abbreviations and the point where languages switch.
Resolve a language list that cannot load or save
If the list cannot load, check your sign-in and connection, then choose Retry. Existing selections are preserved while the app cannot confirm the supported list. A missing list does not prove that a particular language is unsupported.
A choice marked as needing attention means the current service does not support that saved selection. Deselect it or choose automatic detection after the list loads. If the app says changes are not saved, resolve the message before assuming that your next recording will use the new choices.
Use the dictionary for recurring names
When one product name or technical term repeatedly comes out wrong but the rest of the sentence is clear, add its intended spelling to your Dictionary. A relevant entry is more useful than changing every language setting to solve one name.
If ordinary words are also missing or distorted, first check the microphone, background noise and input level. Dictionary entries and language hints can guide recognition, but neither can recover speech the microphone did not capture clearly.
Choose translation separately from recognition
Selecting English as a recognition hint does not instruct SayDart to translate a Chinese passage into English. For voice translation, choose a language in Settings > Voice & translation > Translation > Translate to and press your Translation shortcut (Right Shift + Right Alt on Windows, Right Shift + Right Option on Mac, Left Ctrl + Left Alt + Y on Linux). You can also ask the assistant for a translation. Review the result before placing it in a document or message.
