I sometimes get cut off in the middle of speaking.
The end-point detection feature can be turned on/off from the settings. Please refer to "Settings" in the manual for further details.

If any of the above does not apply, the error may be due to an issue with the specific device or OS version.

"Report an error"
What is "Meaning of translated message."?
The "Meaning of translated message." field shows the translation of the translated sentence into the input language. If the meaning is the same as that of the text in the “Text entered” field, the translated message is considered to be appropriate.
If what you see here is different from what you intended to say, please restate your input and try again.
Where do the speech recogntion and translation processes take place?
They are processed in the cloud. Therefore, Internet connection is required.
Can I use the app without any network connectivity?
The process takes place in the cloud and so network connection is required to use the app. However, the "History" list is available without any network.
