Google Talk has been one of the most easiest and most reliable talking application by which we can manually operate our smartphone by just for voice. For example if we have to call someone or text someone or search for any location then we can use Google talk for this purpose. Moreover Google Talks helps us to keep a reminder and to create any event so that we can get easily notified. Google Talk help us to open apps from our smartphone, and this helps us to access easily. Mostly I use Google talk for my for my accessibility. To Open Google Talk feature you have to say Ok Google. Now the Google Talk has been started for example if you have to call someone then you should say call and then say the user name. Then for example if you have to text someone then you have to say text and the username and Google Talk asks you to say what the message is, then you have to say the whole message. Then after saying are completing the message you have to wait for a while untol google is ready to send, after this you have to say send so that the message will be sent to the person. Then for example if you have to create an event then say create an event and then the name of event. Then say, if you have to turn on your flashlight then you must say, OK Google then turn on flashlight and vice versa. Like this there are many examples which you can manually operate by just your voice. I have found this application to be very useful and I think this will prove very useful and helpful to all other also.
