One of the demands that Apple users usually make with the Siri voice assistant is that it improve and improve and improve ... It is normal to find deficiencies in this assistant taking into account the data that it does not directly collect from the user. This does not mean that Apple does not want to improve the functions and therefore it has programs or applications as in this case Accessed by some invited users (on iOS) to enhance Siri functionality.
Siri Speech Study is an app to improve the Siri assistant
In this case Siri Speech Study, it is a hidden application that found the web page TechCrunch and that possibly if it had not been filtered in this medium we would not have met most of the users. It is about improving the Virtual assistant and for this an invitation is required, it is not something public. It must also be said that this application is not active in all countries, only some have this app active that allows to help Apple with the improvement of the assistant: USA, Germany, France, Canada, Hong Kong, India, Ireland, Japan, Italy, Mexico, New Zealand or Taiwan.
You do not have to search for this application or tool in the Apple application store since You will not be able to use it if you do not have an invitation. Anything that is improving Siri will be welcomed by the rest of the users so it seems to us an interesting option for the Cupertino company.
