解決C#中結賬時金額數字語音播報

先把需要的文件錄製出來, 可以去百度上錄製一下
可以使用百度語音合成: https://developer.baidu.com/vcast

然後把需要轉換的數字Tostring(“F2”)，這裏不要轉N2，不然會有逗號分隔的，我這裏設計只支持到小於一億元的播報。直接上代碼

 public void PayAuido(decimal payMoney)
{
    if (payMoney >= 100000000 || payMoney == 0)
    {
        return;
    }
    Task.Run(() =>
    {
        List<string> payAuidoUrls = new List<string>();
        string payString = payMoney.ToString("F2");
        //如果小於11位，則補零
        if (payString.Length < 11)
        {
            payString = payString.PadLeft(11, '0');
        }
        string payWan = payString.Substring(0, 4);//取得'萬'單元
        string payYuan = payString.Substring(4, 4);//取得'元'單元
        string payNum = payString.Substring(9, 2);//取得小數部分

        //判斷請付
        List<string> payAuidoUrlsFK = Converts(payWan);
        if (this.lblPay.Text == "還應支付")
        {
            payAuidoUrlsFK.Add($"{Application.StartupPath}\\auido\\qf.wav");
        }
        else
        {
            payAuidoUrlsFK.Add($"{Application.StartupPath}\\auido\\zl.wav");
        }
        //處理萬
        List<string> payAuidoUrlsWan = Converts(payWan);
        if (payAuidoUrlsWan.Count > 0)
        {
            payAuidoUrlsWan.Add($"{Application.StartupPath}\\auido\\wan.wav");
        }
        //處理元
        List<string> payAuidoUrlsYuan = Converts(payYuan);

        //元第一個字符是否爲‘零’
        if (payAuidoUrlsWan.Count > 0 && payAuidoUrlsYuan.Count > 0 && payString[4] == '0')
        {
            payAuidoUrlsWan.Add($"{Application.StartupPath}\\auido\\yuan.wav");
        }

        payAuidoUrls.AddRange(payAuidoUrlsFK);
        payAuidoUrls.AddRange(payAuidoUrlsWan);
        payAuidoUrls.AddRange(payAuidoUrlsYuan);

        //處理小數位
        if (payNum != "00")
        {
            //如果只有小數，則添加‘零’
            if (payAuidoUrls.Count == 0)
            {
                payAuidoUrls.Add($"{Application.StartupPath}\\auido\\0.wav");
            }

    if (payAuidos[0].Contains("0.wav"))

    }
    //如果最後一個音頻爲零，則去掉
    if (payAuidos[payAuidos.Count - 1].Contains("0.wav"))
    {
        payAuidos.RemoveAt(payAuidos.Count - 1);
    }
    return payAuidos;
}

需要調用時，直接調用傳值即可

	//語音播報
	PayAuido(Convert.ToDecimal(123.4));

希望可以幫助到大家！
