An example of Speech Recognition

I. Summary

I completed the example in the SDK yesterday and tried to write one by myself according to the document. However, it would be a miracle to directly use the code in the document to call something out.

So it took some time to complete the speech dictation example. In this example, you can click the bottom button to start talking. After that, the textview on the screen will display what you just said.

To be honest, the document is really poorly written, the interface is not detailed, the demo is not described, and there are few notes... alas.

2. Preparations

First of all, create an android project and add a library as described in the document.

1. Select a job in eclipse and introduce MSC. Jar through project> Properties> JAVA buildpath> libraries> Add jars or add external jars;

2. Copy the libs folder under SDK. \ Lib to the project root directory to ensure that the. \ libs \ armeabi \ libmsc. So file exists.

3. Add the following permissions to the androidmanifest. xml file of the project:
<Uses-Permission Android: Name = "android. Permission. record_audio"/>
<Uses-Permission Android: Name = "android. Permission. Internet"/>
<Uses-Permission Android: Name = "android. Permission. access_network_state"/>
<Uses-Permission Android: Name = "android. Permission. access_wifi_state"/>
<Uses-Permission Android: Name = "android. Permission. change_network_state"/>
<Uses-Permission Android: Name = "android. Permission. read_phone_state"/>

Iii. Main Code:
