使用VB.NET 2008进行文本到语音转换

Question

text-to-speech for English language using Visual Basic 2008

Dim speech As Object = CreateObject("SAPI.SpVoice") 
speech.speak(TextBox1.Text) 

My question, how this can be used for other languages(Spoken Languages!!!)? thanks

Answer 1

The SAPI interface got a nice wrapper in .NET 3.0, System.Speech.Synthesis namespace. Usable in any .NET compatible language. Use Project > Add Reference and select System.Speech. Write code similar to :

 Imports System.Speech.Synthesis
 ...
    Dim synth = New SpeechSynthesizer
    synth.Speak("Works in any .NET language")

Answer 2

The Sapi interface is a COM-interface. You can use this with most languages (on windows) which support COM, eg PHP, C, VBA, ...

...but if you mean real-world languages, you have to install additional "voices"

You can also have this below as your code for embedding a text reader into your program;

Imports System.Speech
Imports System.Speech.Synthesis

........

Dim reader As  SpeechSynthesizer =  New SpeechSynthesizer

......
Reader.SpeakAsync(textbox1.text)
Reader.SpeakAsync("The above code assigns reader to read the text in textbox1")
