App Description

“What is the weather tomorrow?” “Check the last train to Yokohama” “Wake up at 6 o'clock” “Remind me at 18:30”

LINE Conversational Voice Agent App (Free) by Yahoo!


[End of Support for Android 7 and Below]
To ensure a safer experience with our voice assistant service, we will be discontinuing support for Android 7 and below, starting with app version 3.25.0.
You can still use voice assistant after support ends, but you will no longer be able to update to the latest version of the app. Thank you for your understanding.

With Yahoo! Voice Assistant, you can get the answers you need just by talking to your smartphone.
Just say, "Will it be sunny tomorrow?", "Find out the last train to Jiyugaoka," or "How tall is Mt. Fuji?" and your voice assistant will look it up on LINE Yahoo! and tell you the answer, just like a secretary.

You can also set an alarm by saying, "Wake me up at 7:45 AM," and it will gently wake you up with a melody that changes depending on the day's weather. After waking up, it will provide you with a summary of the day's news and fortune, providing powerful support for your busy mornings.
Furthermore, by stating a message such as "Remind me at 1:30 PM" or "Call me when I arrive at Shinjuku Station," the voice assistant will remind you at the specified time or location.

You can also change your smartphone settings or launch apps by simply saying "Turn off WiFi" or "Launch camera."

Why not make using your smartphone even easier and more convenient with Yahoo! Voice Assistant?

【Features】
It responds when you speak.
For example, try saying the following:
"First train from Tokyo to Osaka." "Will it be sunny tomorrow?"
"Where am I?" "Nearby convenience store."

"Remind me at 7:00 PM." "Call when I arrive at Tokyo Station."
"Launch the calculator." "Launch LINE."
"What's the battery level?"

"Tell me the election news." "What is Argentina's currency?"
"Let's play a word chain game." "Sing a song." "Word association game."
When you talk to it, it understands what you're saying, looks up the information you want to know on LINE Yahoo, and responds verbally.
Supports route search, weather, maps, store information, news, stock prices, currency exchange, fortune telling, recipes, sports (professional baseball and J.League), and voice search. Voice control is also possible, including making calls, searching for contacts, launching apps, and setting alarms. It can also be used as a conversation partner for simple conversations.

Alarm Function
- Set the alarm with your voice (you can also set it by touching the screen).
- Wake up with seven different alarm sounds based on the weather, so you'll know the weather as you wake up. You can set your favorite song as the alarm sound.
- After stopping the alarm, the voice assistant will greet you like a wake-up call and provide weather information.
- If you're having trouble waking up, try the "Speak to Dismiss" function. The alarm will not stop until you correctly pronounce the four-digit number displayed (it will stop even if you fail five times).
