Techniques for generating a recommendation for content based on user-device dialogue are described. In an example, a computer system receives a request for audio output at a user device. The computer system determines a response for the request. The computer system determines a topic and value associated with the request and the response. The computer system also determines a recommendation for content based on the request and the response. The computer system generates prompt data including a question of whether to initiate an action associated with the recommendation. The computer system sends the prompt data and the response data to the user device or a different user device.

Generating content recommendation based on user-device dialogue

Techniques for identifying and correcting synchronization errors for a media file are described herein. A first file that includes a first set of words comprising lyrics of a media file may be maintained. One or more portions of the media file that represent vocal audio may be separated from other portions of the media file that represent instrumental audio by a computer system. A second file may be generated based at least in part on using an automated speech recognition on the separated one or more portions of the media file. The second file my include time stamps for a second set of words comprising the lyrics in the separated one or more portions of the media file. The first file may be modified with an offset time value that is determined by aligning the first set of words with the second set of words.

Lyrics synchronization

Audio data is received, for example from a voice communications device, and using commands and contexts in the audio data, playback of a content item such as a song can be accomplished. For example, a user can skip ahead in a song, play a song, find a song, and otherwise perform control functions on a device with no screen that give the user contextual control over the song that is playing or is to be played.
