Text-To-Speech (TTS)

Text-to-speech is one of the most important tools that you will need to give Misty a voice. You can select your favorite language and insert a text value block with your unique text to have Misty say it in the language that you've chosen.

You can adjust the pitch of Misty's voice from 0 (Deep), 1 (Default) to 2 (High).

Here you can find a list of all the languages that Misty can speak:

Arabic, Bengali, Chinese, Czeck, Danish, German, Greek, English, Spanish, Estonian, Finnish, Filipino, French, Gujarati, Hindi, Hungarian, Indonesian, Italian, Japanese, Khmer, Kannada, Korean, Malayalam, Mandarin Chinese, Norwegian, Nepali, Dutch, Polish, Portuguese, Romanian, Russian, Sinhalese, Slovac, Sundanese, Swedish, Tamil, Thai, Turkish, Ukrainian, Urdu, Vietnamese.

In most of these languages, you can select a male or female voice, but we suggest using the female one because it matches Misty's character and personality more. Afterall, she was designed to be the power girl of the robot world.

Stop speaking

If Misty is speaking and you want her to stop at a specific point, you can use a timer block and the stop speaking block to let her know.

Speech and Keyphrase recognition

Speech recognition allows Misty to record your speech and convert it into text that she can understand. This tool will be essential when you start creating conversations with Misty. The keyphrase recognition blocks use speech recognition to record specific keywords or keyphrases. These can be useful when you want to trigger sequences using a word or a phrase. The default keyphrase for Misty is 'Hey Misty'.

Once you've trained your Misty to recognize specific words you can use these two blocks in order to start or end Misty's "listening mode" for keyphrases. When Misty will show you that she is listening by turning her head tally light blue.

Capture speech

capture speech block

This block starts capturing speech in a new audio recording. By default, Misty's chest LED pulses blue when she is recording audio or listening for the key phrase. Misty's head tally light also turns on when she is recording audio or video.

Misty waits to start recording until she detects you speaking. She then records your speech until she detects the end of a question or statement. By default, Misty records speech up to 7.5 seconds.
