A method and an apparatus detect an echo delay. If an electronic device plays an audio and a counter is in an on state, an Nrecording data block received after the counter is turned on is acquired, where the Nrecording data block is a currently received recording data block, and N is greater than 1. Matching is performed between the Nrecording data block and a reference data block that is in a buffer, where the recording data block and the reference data block are data blocks with target duration. After the counter is on, the buffer buffers an audio data block played by the electronic device. If the Nrecording data block matches the reference data block in the buffer, a counting value is acquired. The counter performs counting if the recording data block does not match the reference data block. An echo delay is determined based on the target duration and the counting value.

Embodiments of the present disclosure disclose a method and apparatus for displaying navigation routes. The method includes: receiving, from a navigation server, at least two navigation routes from a navigation starting point to a navigation destination; determining a current navigation route from the navigation routes according to selection by a user, and assigning remaining routes as backup navigation routes; and displaying, in a navigation map, the current navigation route in a first mode and displaying the backup navigation routes in a second mode different from the first mode. In the embodiments of the present disclosure, by using the technical solution, the user may clearly and conveniently distinguish the current navigation route from the backup navigation routes, thereby improving the user experience.
