This also allowed users to interact with objects with the controllers while they spoke instead of choosing one or the other. In our environment, you could create or destroy objects at any place and time so we switched from a voice button to ambient listening. api IAMAuthenticator (apikey) speechtotext SpeechToTextV1 (authenticatorapi) tserviceurl (url) with open (mp3-file, 'rb') as audiofile: result speechtotext.recognize ( model'de-DEBroadbandModel', audioaudiofile, contenttype'audio/mp3' ). This indicated that if there is a button to speak, the natural inclination is to speak to that button. They would also hold the controller up to their mouth as if there was a microphone inside (which there wasn't). Once the users went through the tutorial, they had a framework of what they could actually do in the space.Īt first, we designed the experience to have a "push-to-talk" button on the controller, but users quickly forgot it was there or forgot which button it was. To rein them in and have them avoid unsupported commands, we added in a tutorial that let the user know what aspects of the environment can be affected by voice and which commands to use. Eventually, they got frustrated and gave up because nothing was working. When a user voiced an unsupported command, they would wait to see what happens and then try another similar command. They went in all kinds of directions, since technically, there is no limit to voice (unlike a remote, etc.). As soon as we added the laser pointer to the game, users were able to intuitively direct their speech towards the pointer and therefore became much more comfortable speaking.Īt first, we allowed the users to ask anything, just to see what they wanted to do in the environment.
Users would also use speech commands less often if they didn't know where to point their voice or what to say. Without audio prompts, users would kind of stand there and awkwardly not do anything, waiting for some kind of direction. for professionals skilled at building models that analyze speech and language, uncover contextual patterns, and produce insights from text and audio. Users feel more comfortable talking to someone/something or have a direction to speak.

In the tool, the name of an entity is always prefixed with the character.The first thing we learned was that users prefer to direct their speech at an action or object instead of talking into empty space. By recognizing the entities that are mentioned in the user’s input, the Watson Assistant service can choose the specific actions to take to fulfill an intent. You list the possible values for each entity and synonyms that users might enter. The following are examples of intent names.Īn entity represents a term or object that is relevant to your intents and that provides a specific context for an intent. Simply put, intents are the intentions of the end-user. In the tool, the name of an intent is always prefixed with the # character. By recognizing the intent expressed in a user’s input, the Watson Assistant service can choose the correct dialog flow for responding to it. Many giant tech companies have their own recognition models. You define an intent for each type of user request you want your application to support. Here are the steps we will follow in this speech recognition project. Copy and save the Workspace ID for future reference.Īn intent represents the purpose of a user’s input, such as answering a question or processing a bill payment.
