如果您只想播放消息而不需要用户输入,可以使用Message
该类:
//Play a synthesis message in another language
Message message = new Message("synthesis-french-message",
new SpeechSynthesis("Ceci est un message."));
message.setLanguage("fr-CA");
DialogueUtils.doTurn(message, context);
如果您需要在 中指定提示的语言Interaction
,可以使用InteractionBuilder
. 该setLanguage()
方法可以在该addPrompt()
方法之前使用。在同一交互中可以使用多种语言:
Interaction interaction = OutputTurns.interaction("multilingual-interaction")
.setLanguage("es-ES")
.addPrompt(new SpeechSynthesis("Holá."))
.setLanguage("fr-CA")
.addPrompt(new SpeechSynthesis("Bonjour."))
.build(new SpeechRecognition(new GrammarReference("grammar.grxml")),
Duration.seconds(2));
DialogueUtils.doTurn(interaction, context);
如果您不想使用构建器,您可以手动完成,但时间要长得多:
List<Interaction.Prompt> prompts = new ArrayList<Interaction.Prompt>();
Interaction.Prompt spanishPrompt = new Interaction.Prompt(new SpeechSynthesis("Holá."));
spanishPrompt.setLanguage("es-ES");
prompts.add(spanishPrompt);
Interaction.Prompt frenchPrompt = new Interaction.Prompt(new SpeechSynthesis("Bonjour."));
frenchPrompt.setLanguage("fr-CA");
prompts.add(frenchPrompt);
SpeechRecognition speechRecognition = new SpeechRecognition(new GrammarReference("grammar.grxml"));
FinalRecognitionWindow finalRecognitionWindow = new FinalRecognitionWindow(speechRecognition,
Duration.seconds(2));
Interaction interaction2 = new Interaction("multilingual-interaction2",
prompts,
finalRecognitionWindow);
DialogueUtils.doTurn(interaction2, context);
输出 VoiceXML 是:
