編輯和運行Windows Phone應(yīng)用是件很容易的事情，你只需在微軟網(wǎng)站獲取一個免費的工具包，在AppHub注冊后，并跟著入門教程學(xué)習(xí)就可以了。

XAML是我的慣用格式。. WP7開發(fā)者也許能注意到應(yīng)用程序標(biāo)題和頁名不再是默認(rèn)的硬編碼，而是通過通過應(yīng)用的共享資源來實現(xiàn)。通過這種方式，你不必再每次再所有頁中設(shè)置應(yīng)用名稱。

下面是.xaml主頁的代碼文件。其內(nèi)容大部分借用自WP8 SDK的文檔。我加入了一些錯誤檢測的內(nèi)容以及性別選擇和發(fā)音語言選擇的功能。

using System;using System.Linq;using System.Windows;using Microsoft.Phone.Controls;using Windows.Phone.Speech.Synthesis; namespace TextToSpeechDemo{    public partial class MainPage : PhoneApplicationPage    {        SpeechSynthesizer synth;        // Constructor        public MainPage()        {            InitializeComponent();            voicesComboBox.ItemsSource = new MyLocals().Items();        }         private async void SpeakToMe_Click(object sender, RoutedEventArgs e)        {            if (voicesComboBox.SelectedIndex == -1)            {                MessageBox.Show("Please select a language.");            }            else            {                if (string.IsNullOrEmpty(inputTextBox.Text))                {                    MessageBox.Show("Please enter some text.");                }                else                {                    try                    {                        // Initialize the SpeechSynthesizer object.                        synth = new SpeechSynthesizer();                         var myLocal = (MyLocale)voicesComboBox.SelectedItem;                         // Query for a voice. Results rdered by Gender to ensure the order always goes Female then Male.                        var voices = (from voice in InstalledVoices.All                                      where voice.Language == myLocal.Lcid                                      select voice).OrderByDescending(v => v.Gender);                         // gender: 0 = Female, 1 = Male. Corresponds to the index of the above results.                        int gender = 0;                        if (MaleRadioButton.IsChecked == true) gender = 1; else gender = 0;                         // Set the voice as identified by the query.                        synth.SetVoice(voices.ElementAt(gender));                         // Speak                        await synth.SpeakTextAsync(inputTextBox.Text);                    }                    catch (Exception ex)                    {                        MessageBox.Show(ex.Message);                    }                }            }        }    }}

下面兩個類是用來填充發(fā)音語言的下拉列表框和檢測安裝的聲音。 里面包含30項（15種語言 x 2種聲音)。 通過LINQ查詢可以獲取所需的聲音信息對象，這里可以給出12種語言，而另外3種仍需深入了解。

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks; namespace TextToSpeechDemo{    class MyLocale    {        public MyLocale(string name, string lcid)        {            _name = name;            _lcid = lcid;        }         private string _name;        public string Name        {            get { return _name; }            set { _name = value; }        }         private string _lcid;        public string Lcid        {            get { return _lcid; }            set { _lcid = value; }        }    }     class MyLocals    {        private IList<MyLocale> _myLocals;         public MyLocals()        {            _myLocals = new List<MyLocale>();             _myLocals.Add(new MyLocale("Chinese Simplified (PRC)", "zh-CN"));            _myLocals.Add(new MyLocale("Chinese Traditional (Taiwan)", "zh-TW"));            _myLocals.Add(new MyLocale("English (United States)", "en-US"));            _myLocals.Add(new MyLocale("English (United Kingdom)", "en-GB"));            _myLocals.Add(new MyLocale("French (France)", "fr-FR"));            _myLocals.Add(new MyLocale("German (Germany)", "de-DE"));            _myLocals.Add(new MyLocale("Italian (Italy)", "it-IT"));            _myLocals.Add(new MyLocale("Japanese (Japan)", "ja-JP"));            _myLocals.Add(new MyLocale("Polish (Poland)", "pl-PL"));            _myLocals.Add(new MyLocale("Portuguese (Brazil)", "pt-BR"));            _myLocals.Add(new MyLocale("Russian (Russia)", "ru-RU"));            _myLocals.Add(new MyLocale("Spanish (Spain)", "es-ES"));        }         public IEnumerable<MyLocale> Items()        {            return (IEnumerable<MyLocale>)_myLocals;        }    }}

接下來的事情是設(shè)置 ID_CAP_SPEECH_RECOGNITION功能，否則將拋出異常。

現(xiàn)在，我們?nèi)绻\行應(yīng)用將得到下面的結(jié)果，選擇一種語言并單擊按鈕，則這個仿真器會與你交談。

我注意到一件事：如果我選擇一個非英語語言而輸入英語文本的話，則其發(fā)音帶有口音。當(dāng)我將文本設(shè)置為發(fā)育的數(shù)字文本：1, 2, 3, 4，同時將語言設(shè)置為與法語相似的語言（如西班牙語），則其對“4”的發(fā)音是西班牙語，而非法語，這聽起來很有趣。
