How to use Text to Speech in Android

Initialize the texttospeech object.

mtts = new texttospeech(this,this //

Implement the interface detection initialization state.

Implement the void oninit(int status) method of the oninitlistener interface to check whether the initialization status is successful.

After the object is used, call the shutdown method to release the resources occupied by the TextToSpeech (TTS) engine.

TextToSpeech, or TTS for short, is one of the more important new features in the Android version. Converts the specified text into audio output in different languages. It can be easily embedded in games or applications to enhance the user experience.

Before we get into the TTS API and how to apply this functionality to your real project, let's get a first look at the TTS engine.

A general understanding of TTS resources:

TTS Engine relies on the five major languages supported by the current Android Platform: English, French, German, Italian and Spanish (there is no great Chinese for the time being, at least Google scientists have not played Chinese to the point of pure fire, and it is natural to make it easy and then difficult). TTS can convert text into speech output in any of the five languages listed above.

At the same time, individual language versions will depend on different time zones, for example: for English, two different versions of American and British can be output in TTS (which shows that Google's style of doing things is really meticulous, and because of this, it is estimated that another reason why Google does not add Chinese is that there are too many dialects of Chinese).

To support such a large amount of data, the TTS engine takes a pre-loading approach to resource optimization. According to a series of parameter information (the usage of parameters will be described in detail later), the corresponding resources are extracted from the library and loaded into the current system.

Although most of the devices loaded with the Android operating system provide TTS functions through this engine, due to the very limited storage space of some devices, TTS cannot maximize the function, which is a bottleneck at present. To this end, the development team has introduced a detection module so that applications or games that use this technology can be optimized for different devices, so as to avoid affecting the use of the entire application due to the limitations of this function. It is safer to let the user choose whether there is enough space or demand to load this resource, and a standard detection method is given below:

checkintent = new intent();my_data_check_code);

Use iFLYTEK TTS voice library (Chinese only), in addition, the software should support text reading such as static reading world, and other voice libraries under English are set in settings, language and input methods, and text-to-speech.

It is to give the text, and the pronunciation corresponding to the text can be pronounced from the speaker.

Many times we will encounter text-to-speech needs, using a third-party SDK is a good choice, in fact, it can also be simpler, Android natively provides a class to handle this transaction. TextToSpeech doesn't need to be integrated and can be used directly.

You have to develop a language pack by yourself, not just one person, at least a team.

The way to do this is to have a full recording to pause! In other words, you have to wait for the complete reading to achieve this kind of function!

You can call setstreamvolume() on the audiomanager. or setSpeechRate() method.
