Once you enable the talkback feature and choose male/female voice as required, Tellius Assistant will respond to your questions in voice format. In addition to the text format responses, Tellius Assistant speaks out the responses using the text-to-speech mode.

The mic (in the rightmost corner) can be enabled, and you can ask your questions through the mic. With the help of Active Speech Recognition (ASR), Tellius Assistant interprets every word in your queries and provides suitable responses in voice and text format.

Even if you take a pause or leave the question incomplete, Tellius Assistant understands and waits for you to resume speaking. In rare cases when Tellius Assistant fails to understand your question, it suggests a list of related questions.

To receive the best experience, make sure you turn off Chrome extensions and have the latest Chrome installed.
