你是我的眼，也是我的嘴——利用萤石摄像头TTS播报

telanx

厉害了楼主，佩服大神。
一直想在门口弄个音响TTS，提醒是否下雨等，这下用摄像头兼顾了，哈哈哈
后续再研究下萝卜大神说的，微信语音直接推送到音响TTS出来就更牛了。

感谢楼主分享，顺便提示一点，我发现萤石下发语音文件时，好像对语音文件时长有限制，我有一段回家的提醒，文字比较长，下发时提示语音文件时长错误，当我尝试提高百度tts语速或者减小这段话的长度时，播放正常，由于我没有本地保存tts文件，所以还无法测试具体的时长限制，我已经在萤石上发了工单询问。
我回家的提醒如下：女士，欢迎您回家！现在是2021年11月18日晚上10点54分。家中温度为摄氏23.3度，室内温度适宜。家中空气质量一级，优！aqi指数为44。系统探测到室外空气很糟糕，室内空气很清新，建议您一定紧闭所有门窗，必要时手动开启空气净化器和新风系统。今日空气净化系统已经运行了76分钟，剩余44分钟净化时间将在您下次离家的时候完成。我在关闭监控过程中出现了问题，系统检测监控尚未完全关闭，建议您手动检查。您已经离开家24小时，期间，妈妈曾经在家,在妈妈离开家的8小时时间里，我曾经检测到有1次有人在家中活动，强烈建议您检查是否正常！信息播报完毕，祝您在家愉快。

另外，可以使用我这个流，直接调用百度语音的api接口，返回的二进制的语音文件直接传给萤石api，可以避免保存本地tts文件。

你这个问的太宽泛了，不好排除故障啊。根据现在你提供的线索，只能证明要么是百度TTS节点没有正确生产语音文件数据，要么就是语音文件数据没有正确传给萤石云。建议你多拉几个debug出来看看到底哪里的数据不正确。

流是复制您的，我看debug内容应该是没有msg.data

inject节点内容有填写msg.data

我检查了看baidutts 也没问题啊

你的截图里不是都写的很清楚了吗？“语音合成失败，请检查配置”

问题肯定就在百度TTS那里，看看是不是百度TTS的配置填错了，或者是不是百度云有什么问题了，去百度云看看，有没有开通TTS应用，有没有申请TTS额度。
