c#文本转语音以及语音阅读小实例

资料来源：网络整理时间：2023/2/14 0:44:48 共计：3615 浏览

c#实现语音阅读以及文本转语音文件是基于c#的一个类库（SpeechSynthesizer ）实现的，使用该类必须要添加引用using System.Speech.Synthesis;直接是无法添加引用的，先对项目进行添加应用

示例图

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Speech.Synthesis;
using System.Text;
using System.Threading;
using System.Windows.Forms;

namespace 文本转语音Demo
{
public partial class Form1 : Form
{
private SpeechSynthesizer speech;

/// <summary>
/// 音量
/// </summary>
private int value=100;
/// <summary>
/// 语速
/// </summary>
private int rate;
public Form1()
{
InitializeComponent();

comboBox1.SelectedIndex = 10;
}

private void button1_Click(object sender, EventArgs e)
{

string text=textBox1.Text;

if (text.Trim().Length == 0) {
MessageBox.Show("不能阅读空内容!","错误提示");
return;
}

if (button1.Text == "语音试听") {

speech = new SpeechSynthesizer();

new Thread(Speak).Start();

button1.Text = "停止试听";

}else if(button1.Text=="停止试听"){

speech.SpeakAsyncCancelAll();//停止阅读

button1.Text = "语音试听";
}
}

private void Speak() {

speech.Rate =rate;
speech.SelectVoice("Microsoft Lili");//设置播音员（中文）
//speech.SelectVoice("Microsoft Anna"); //英文
speech.Volume = value;
speech.SpeakAsync(textBox1.Text);//语音阅读方法
speech.SpeakCompleted += speech_SpeakCompleted;//绑定事件
}

/// <summary>
/// 语音阅读完成触发此事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
void speech_SpeakCompleted(object sender, SpeakCompletedEventArgs e)
{
button1.Text = "语音试听";
}

/// <summary>
/// 拖动进度条事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void trackBar1_Scroll(object sender, EventArgs e)
{
//因为trackBar1的值为（0-10）之间而音量值为（0-100）所以要乘10；
value = trackBar1.Value * 10;
}

private void button2_Click(object sender, EventArgs e)
{

string text = textBox1.Text;

if (text.Trim().Length == 0)
{
MessageBox.Show("空内容无法生成!", "错误提示");
return;
}

this.SaveFile(text);

}

/// <summary>
/// 生成语音文件的方法
/// </summary>
/// <param name="text"></param>
private void SaveFile(string text) {
speech = new SpeechSynthesizer();
var dialog = new SaveFileDialog();
dialog.Filter = "*.wav|*.wav|*.mp3|*.mp3";
dialog.ShowDialog();

string path = dialog.FileName;
if (path.Trim().Length == 0)
{
return;
}
speech.SetOutputToWaveFile(path);
speech.Volume = value;
speech.Rate = rate;
speech.Speak(text);
speech.SetOutputToNull();
MessageBox.Show("生成成功!在" + path + "路径中！", "提示");

}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
rate = Int32.Parse(comboBox1.Text);
}

private void 打开文件ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.ReadlocalFile();

}

/// <summary>
/// 读取本地文本文件的方法
/// </summary>
private void ReadlocalFile() {
var open = new OpenFileDialog();

open.ShowDialog();

//得到文件路径
string path = open.FileName;

if (path.Trim().Length == 0)
{

return;
}

var os = new StreamReader(path, Encoding.UTF8);
string str = os.ReadToEnd();
textBox1.Text = str;
}
private void 清空内容ToolStripMenuItem_Click(object sender, EventArgs e)
{
textBox1.Text = "";
}

}
}
