摘要： A method and apparatus for processing audio for playback to provide a smooth transition between a beginning region of an audio track and an end region of a previous audio track is disclosed. A quantity representative of a chromagram is calculated for each of the audio tracks and the mixing points for the beginning and end regions of each audio track are identified. A quantity representative of a chromagram at the mixing point of the beginning region of the audio track and a quantity representative of a chromagram at the mixing point of the end region of the previous audio track are correlated to determine an order of audio tracks for playback and/or to determine the duration of the mix transition.

摘要： An apparatus with a speech control unit includes a microphone array having multiple microphones for receiving respective audio signals, and a beam forming module for extracting a speech signal of a user, from the audio signals. A keyword recognition system recognizes a predetermined keyword that is spoken by the user and which is represented by a particular audio signal and is arranged to control the beam forming module, on basis of tie recognition. A speech recognition unit creates an instruction for the apparatus based on recognized speech items of the speech signal. As a consequence, the speech control unit is more selective for those parts of the audio signals for speech recognition which correspond to speech items spoken by the user.

摘要： When playing back content identified on the playlist, it is determined if each of the content items is available. For a given content item that is not available, an additional content item (relevant content item) that is available and that corresponds to selection criteria is determined. The relevant content item and/or a new playlist is presented to a user for approval. The selection criteria is expanded to include a content item not previously identified if an additional content item is not available or is not approved.

摘要： Techniques are presented for selecting one or more items from a collection of items. To select the one or more items, an interface is provided that is adapted to allow a user to define one or more weights. Each weight corresponds to one of a number of similarity criteria. Each item also corresponds to the number of similarity criteria. The one or more weights define a similarity function. The similarity function is applied to the one or more similarity criteria corresponding to the one or more weights and to each of the items in order to select one or more items from the collection of items. The interface can comprise movable markers corresponding to similarity criteria. Locations of the movable markers can be used to weight similarity criteria when creating the similarity function.

摘要： A playlist generator partitions the playlist generation process into a multi-stage, hierarchical process. At an example highest hierarchical level, the user's “general” preferences are applied. These general preferences reflect the user's “tastes”, and are relatively constant. At a lower level of the hierarchy, the user's “specific” preferences are applied. These specific preferences reflect the dynamic time-dependent or event dependent aspects of a user's entertainment preferences. The high-level preferences generate a subset of material from the global collection of material, and the lower-level preferences are applied to this subset of material as the user's immediate preferences change. By segregating the playlist generation process hierarchically, efficiency is gained by applying immediate preference changes to a smaller subset of material, and coherency is improved by limiting the subsequent selection processes to a given subset of the material.
摘要翻译： 播放列表生成器将播放列表生成处理分割成多级分层处理。 在最高级别的例子中，应用用户的“一般”偏好。 这些一般偏好反映了用户的“口味”，并且相对不变。 在层次结构的较低级别，应用用户的“特定”首选项。 这些具体的偏好反映了用户娱乐偏好的动态时间依赖或事件依赖的方面。 高级偏好从全局材料集合中生成材料的子集，并且当用户的即时偏好改变时，较低级别的偏好将应用于该材料子集。 通过分层分隔播放列表生成过程，通过对较小的材料子集应用即时偏好改变来获得效率，并且通过将随后的选择过程限制到材料的给定子集来提高一致性。

摘要： A system and method for playlist generation is configured to augment a playlist derived from selections from a user's collection with selections from beyond the user's collection. Both the user's collection and external sources are searched for entertainment items that conform to the user's preferences, and the resultant playlist includes a mix of material from both the user's collection and the external sources. The user is provided the option of specifying the proportion of material that is to be included in the playlist from the external sources. If the material from the external sources requires a purchase fee, the user is provided the option of purchasing the material, preferably, after being given the opportunity to view, listen to, or otherwise assess the material.
