有 SSML 的语音标记示例

从 SSML 增强文本生成语音标记的过程与 SSML不存在时的过程相似。使用 synthesize-speech 命令，并指定 SSML 增强文本和您所需的语音标记类型，如下例所示。为了使示例更容易阅读，我们未包含语音视位语音标记，但这些也可以包含在内。

以下 AWS CLI 示例针对 Linux、Unix 和 macOS 编排了格式。对于 Windows，请将每行末尾的反斜杠 (\) Unix 行继续符替换为脱字号 (^) 并在输入文本周围使用全角引号（“），内部标签使用单引号（’）。

aws polly synthesize-speech \
  --output-format json \
  --voice-id Joanna \
  --text-type ssml \
  --text '<speak><prosody volume="+20dB">Mary had <break time="300ms"/>a little <mark name="animal"/>lamb</prosody></speak>' \
  --speech-mark-types='["sentence", "word", "ssml"]' \
  output.txt

当您发出此请求时，Amazon Polly 会在 .txt 文件中返回以下内容：

{"time":0,"type":"sentence","start":31,"end":95,"value":"Mary had <break time=\"300ms\"\/>a little <mark name=\"animal\"\/>lamb"}
{"time":6,"type":"word","start":31,"end":35,"value":"Mary"}
{"time":325,"type":"word","start":36,"end":39,"value":"had"}
{"time":897,"type":"word","start":40,"end":61,"value":"<break time=\"300ms\"\/>"}
{"time":1291,"type":"word","start":61,"end":62,"value":"a"}
{"time":1373,"type":"word","start":63,"end":69,"value":"little"}
{"time":1635,"type":"ssml","start":70,"end":91,"value":"animal"}
{"time":1635,"type":"word","start":91,"end":95,"value":"lamb"}
