Acoustic fingerprint code for iOS?

阅读更多关于 Acoustic fingerprint code for iOS?

问题 I've started looking on the subject of Acoustic Fingerprint (http://en.wikipedia.org/wiki/Acoustic_fingerprint) for a pet project of mine for the iOS and I was wondering if there are: Any opensource libraries or source code for the iOS that handle this? Assuming I'm a veteran jack of all trades coder, is it very problematic to implement this myself if there is no open-source versions? Will the Accelerate DSP library in iOS able to handle such a task? Thanks 回答1: Not of my knowledge No problem

Android catch Bluetooth HFP's Activate Voice Recognition

阅读更多关于 Android catch Bluetooth HFP's Activate Voice Recognition

When Bluetooth hands free device connected to mobile phone, if device sends an AT command AT+BVRA to enable voice recognition, the mobile phone launches the default voice recognition app if it supports.

Simply meaning instead of the login screen where you have to type your password or draw the pattern, you only only need to say one word such as "Login" and the phone authenticates you and automatically unlocks the phone. I was initially planning to implement it on windows but i am afraid that windows might not support voice bio metrics. So

The message content is always in same format and left by the same computer voice with only a slight variation in content: "You sold 4 cars today" (where the 4 can be anything from 0 to 9). I have be trying to set up Sphinx, but the out-of-the-box models did not work too good.

I am wondering if voice recognition might be overkill for this task since I have exactly ONE voice, an expected audio pattern and a

How do I use Android SpeechRecognizer as a service?

阅读更多关于 How do I use Android SpeechRecognizer as a service?

问题 I am trying to run Android voice recognition as a service. I can verify that the onCreate() and onStart() methods of the service are called, but no callbacks to the speech recognition methods are called, despite the fact that I have set up the SpeechRecognizer object correctly. The speech recognition seems to work when it is done in an activity instead of a service. How do I make it work as a service? Is this a manifest issue? package net.viralpatel.android.speechtotextdemo; import java.io
