推荐答案
如果您使用 Google Directions API 接收路线，您会以 JSON 格式接收路线，其中包括路线点、路线长度、预期的持续时间行程和说明.您可以获取它们，然后在需要时使用文本转语音从特定指令中发出声音.
If you're using Google Directions API for receiving directions, you receive them in JSON format which includes the route points, the route length, the expected duration of the trip and the instructions. You can get them and then use text-to-speech to make sound out of the particular instruction when it's time for it.
