telegram - 无法使用带有 Node-Red 的 IBM Watsown Speech to Text 对电报语音消息进行转码

Question

尝试从 Telegram 语音消息中转录音频，但从 watson 的语音到文本节点出现“无法转码数据流音频/作品 -> 音频/x-float-array”错误。

我在 Raspberry 上使用 Node-Red 来简单地使用 node-red-contrib-telegrambot 和 node-red-node-watson 从 Telegram 语音消息中转录音频。

使用短信，我的代码就像一个魅力。使用语音消息时，我从 watson 的语音到文本节点出现“无法转码数据流音频/作品 -> 音频/x-float-array”错误。

更新：Flow 与电报节点 v4.4.0 完美配合，但新版本 5.1.5 失败

因此，对于 Speech to Text 节点，这不是问题。
