使用语音转文本流的Active属性将会话发送到助手

Question

通过修改ExampleAssistant.cs和ExampleStreaming.cs脚本，一旦识别结果为final，我便将消息/讲话发送到Assistant服务，以便在Unity中进行对话，就好像您在键入在聊天框中。

这意味着我必须在Active脚本的false事件处理方法中将OnRecognize属性设置为ExampleStreaming.cs。

但是，一旦发送了语音并且我将其设置回true以继续收听/记录并识别用户的语音，该服务就不会再次启动。

使用调试消息，我已经确认该属性确实设置回true并且执行了StartRecording方法。

private void OnRecognize(SpeechRecognitionEvent result, Dictionary<string, object> customData)
{
    if (result != null && result.results.Length > 0)
    {
        foreach (var res in result.results)
        {
            foreach (var alt in res.alternatives)
            {
                string text = string.Format("{0} ({1}, {2:0.00})\n", alt.transcript, res.final ? "Final" : "Interim", alt.confidence);
                ResultsField.text = alt.transcript;

                /// Only send the recognized speech utterance to Conversation
                /// Assistant once we know the user has stopped talking.
                if (res.final)
                {
                    string _conversationString = alt.transcript;
                    Active = false; /// Stop the microphone from listening.

                    /// Message.
                    Dictionary<string, object> input = new Dictionary<string, object>();
                    input["text"] = _conversationString;
                    MessageRequest messageRequest = new MessageRequest()
                    {
                        Input = input,
                    };

                    _exampleAssistantV1_script.SendMessageAssistant(messageRequest);

                    /// Start listening & recording
                    /// with the microphone.
                    Active = true;
                    StartRecording();
                }
            }
        }
    }
}

实际上，它最终陷入了else属性的Active子句中，这意味着除未设置value以外，其他一切都很好。

有人可以帮助我理解为什么会发生这种情况，或者为什么没有设置属性，或者为什么服务无法恢复？当然，由于未设置属性，该服务不会恢复，但是我在做什么错了？

public 
{
    get
    {
        return _service.IsListening;
    }
    set
    {
        if (value && !_service.IsListening)
        {
            _service.RecognizeModel = ( string.IsNullOrEmpty(_recognizeModel) ? "en-US_BroadbandModel" : _recognizeModel);
            _service.DetectSilence = true;
            _service.EnableWordConfidence = true;
            _service.EnableTimestamps = true;
            _service.SilenceThreshold = 0.01f;
            _service.MaxAlternatives = 0;
            _service.EnableInterimResults = true;
            _service.OnError = OnError;
            _service.InactivityTimeout = -1;
            _service.ProfanityFilter = false;
            _service.SmartFormatting = true;
            _service.SpeakerLabels = false;
            _service.WordAlternativesThreshold = null;
            _service.StartListening(OnRecognize, OnRecognizeSpeaker);
        }
        else if (!value && _service.IsListening)
        {
            _service.StopListening();
        }
    }
}
