vb.net怎么做中文語音識(shí)別程序

這就要調(diào)用API函數(shù)了

VB.NET 打包安裝到目標(biāo)機(jī)后為何沒有了聲音?

在目標(biāo)機(jī)器上查看一下winmm.dll是否正確注冊(cè),如果沒問題,那就是對(duì)方聲卡的問題,再換臺(tái)機(jī)器試試。

Vb(或者VB.net)影像識(shí)別系統(tǒng)

建議用VC做吧,VB圖像處理速度慢。

VC的話其實(shí)不怎么難,簡單學(xué)學(xué)圖像處理,網(wǎng)上現(xiàn)成的程序一把,涉及降噪、圖像二值化、邊界提取、中心計(jì)算等問題,還有回調(diào)函數(shù)也用的到。

如何用vb.net將漢字轉(zhuǎn)換成拼音阿

public string hz2py(string hz) //獲得漢字的區(qū)位碼

byte[] array = new byte[2];

array = System.Text.Encoding.Default.GetBytes(hz);

int i1 = (short)(array[0] - '\0');

int i2 = (short)(array[1] - '\0');

//unicode解碼方式下的漢字碼

// array = System.Text.Encoding.Unicode.GetBytes(hz);

// int i1 = (short)(array[0] - '\0');

// int i2 = (short)(array[1] - '\0');

// int t1 = Convert.ToInt32(i1,16);

// int t2 = Convert.ToInt32(i2,16);

int tmp=i1*256+i2;

VB.NET中怎么實(shí)現(xiàn) 漢字轉(zhuǎn)換拼音

建立一個(gè)表,每個(gè)拼音都跟多個(gè)漢字對(duì)應(yīng)。可以通過漢字,找出對(duì)應(yīng)的一個(gè)拼音,也可以通過拼音,找出一堆漢字。

vb.net 如何識(shí)別換行符?

Dim MultiString as String‘有許多行的字符串Dim StrArray() as String'字符串類型的一維數(shù)組StrArray=Split(MultiString,VbCrlf)'用換行符分割字符串
