SrgsToken.Pronunciation 属性

定义

获取或设置定义标记发音的字符串。

public:
 property System::String ^ Pronunciation { System::String ^ get(); void set(System::String ^ value); };
public string Pronunciation { get; set; }
member this.Pronunciation : string with get, set
Public Property Pronunciation As String

属性值

返回包含在 PhoneticAlphabet 中指定的语音字母表的电话的字符串。

例外

尝试将 Pronunciation 设置为 null

试图将 Pronunciation 指定为空字符串。

示例

以下示例中的语法包含俚语,并且还有一个不常见的单词:“whatchamacallit”。 使用 Pronunciation 类的 SrgsToken 属性添加自定义的内联发音可以提高单词“whatchamacallit”以及包含该单词的整个短语的识别准确性。 该示例使用 Microsoft 通用电话集 (UPS) 中的电话来定义自定义发音。

using System.Speech.Recognition.SrgsGrammar;

          new string[] { "give me", "gimme", "hand me", "ha'me" });
        SrgsOneOf the = new SrgsOneOf(new string[] { "the", "duh" });

        // Build the one-of element that contains the pronunciation.
        SrgsItem thing = new SrgsItem("thingamajig");

注解

电话是描述语音声音的字母或符号。 System.Speech 支持三种用于指定自定义发音的拼音字母:通用电话集 (UPS) 、语音 API (SAPI) Phone 集,以及国际音标 (IPA) 。 中指定的 Pronunciation 电话必须与 中指定的 PhoneticAlphabet拼音字母匹配。 有关详细信息 ,请参阅词典和拼音字母

中指定的 Pronunciation 电话指示应如何发音以成功识别的内容 Text 。 语音识别引擎使用 中指定的 Pronunciation 发音来匹配语音输入,并返回识别结果中包含的字符串 Text

如果电话未用空格分隔或指定的字符串包含无法识别的手机,则识别引擎不会将指定的发音识别为 包含 Text的单词的有效发音。

中指定的 Pronunciation 发音优先于与语法或识别引擎关联的词典中指定的发音。 此外, 属性中的 Pronunciation 发音仅适用于 包含 Text的单词或短语的单个匹配项。
