C # Speech Recognition usage examples

The examples in this article describe the use of C # speech recognition. Share to everyone for your reference. The specific analysis is as follows:

C # can take advantage of the Microsoft operating system's automatic speech recognition function to read information. The steps are as follows:

1. Add "" References in the project

2. Introduce namespaces:

The code is as follows:

Using Speechlib;

3. Read the code:

The code is as follows:

Speechvoicespeakflags flag = Speechvoicespeakflags.svsflagsasync;

SpVoice voice = new SpVoice ();

Voice. Voice = Voice. Getvoices (String. Empty, String. Empty). Item (0);

Voice. Speak ("You are a big beauty, I try a handsome pot, haha", flag);

which

1. Speechvoicespeakflags is an enumeration.

SpVoice Logo:

Svsfdefault = 0

Svsflagsasync = 1

Svsfpurgebeforespeak = 2

Svsfisfilename = 4

Svsfisxml = 8

Svsfisnotxml = 16

Svsfpersistxml = 32

Regularization flag:

Svsfnlpspeakpunc = 64

Mask:

Svsfnlpmask = 64

Svsfvoicemask = 127

Svsfunusedflags =-128

End enumeration molecule

Svsfdefault

Specifies the default settings that should be used. The default values are:

Fixed text string synchronization (overwrite with Svsflagsasync),

Do not clear pending talk requests (overwrite with Svsfpurgebeforespeak),

In order to parse the text of the XML, if the first character is a left angle bracket (overwriting with svsfisxml or svsfisnotxml),

Do not adhere to global XML state changes in the talk call (overwrite Svsfpersistxml),

Do not extend the punctuation word literal (overwrite with svsfnlpspeakpunc).

Svsflagsasync

The specified talk call should be asynchronous. That is, it returns immediately after the queued talk request.

Svsfpurgebeforespeak

Clear all pending speech requests, before speaking of calls.

Svsfisfilename

The way the string is passed is a file name, not a literal. As a result, there is no spoken string itself but the path to the file, which is handled orally.

Svsfisxml

The text entered will be parsed into an XML tag.

Svsfisnotxml

The input text will not be parsed by the XML tag.

Svsfpersistxml

Changes in the global state of the XML tag will persist to the spoken call.

Svsfnlpspeakpunc

, punctuation should be extended to words (for example: "What is this.") "Will become" this is the issue ").

Svsfnlpmask

SAPI (instead of the text-to-speech engine) handles flags in this mask.

Svsfvoicemask

This mask has each flag bit set.

Svsfunusedflags

This mask has every unused bit set.

2. SpVoice

The SpVoice class is a core class that supports speech synthesis (TTS). The TTS engine is invoked through the SpVoice object to enable read aloud functionality.

The SpVoice class has the following main properties:

Voice: Represents the type of pronunciation, which is equivalent to those who speak aloud, including Microsoft Mary,microsoft mike,microsoft Sam and Microsoft Simplified Chinese four kinds. The first three kinds can only read English, the last one can read Chinese, but also can read English, but for English words can only be included in each letter read out. We will find a way to solve this problem in the following procedure.

Rate: The speed of speech reading, the value range is 10 to +10. The higher the value, the faster the speed.

Volume: volume, with values ranging from 0 to 100. The larger the number, the greater the volume.

SpVoice has the following main methods:

Speak: Completes the conversion of text information to speech and reads it according to the specified parameters, which has text and flags two parameters, specifying the text to read aloud and how to read aloud (synchronous or asynchronous, etc.).

Pause: Pauses all the read-aloud processes that use the object. The method has no parameters.

Resume: Resumes the paused read-aloud process corresponding to the object. The method has no parameters.
