如果您使用 Google Directions API 接收路線，您會(huì)以 JSON 格式接收路線，其中包括路線點(diǎn)、路線長(zhǎng)度、預(yù)期的持續(xù)時(shí)間行程和說明.您可以獲取它們，然后在需要時(shí)使用文本轉(zhuǎn)語音從特定指令中發(fā)出聲音.
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.
