Methods, apparatus, systems, and articles of manufacture are disclosed to estimate an audience population. An example apparatus includes processor circuitry; characteristic identifier instructions to be executed by the processor circuitry to determine whether respective ones of respondents are associated with a characteristic; recapture probability estimator instructions to be executed by the processor circuitry to select a recapture probability of the respective ones of respondents; and population estimator instructions to be executed by the processor circuitry to in response to the recapture probability satisfying a recapture threshold, determine a population estimate having the characteristics based on a first model; and in response to the recapture probability not satisfying the recapture threshold, determine the population estimate having the characteristics based on a second model, the second model different than the first model.

In accordance with some implementations, a method for measuring viewership of media content is disclosed. The method is performed on a client system. The client system obtains identification information for individuals who have agreed to participate in a media viewership totals measurement study, detects a first user of the client system, determines media content being presented in proximity to the first user, automatically determines if the first user is an individual who has agreed to participate in the media viewership totals measurement study; and generates viewership data according to the determination.

Techniques for projecting household-level viewing events are described herein. Population data may be accessed including classes of a plurality of demographic attributes for households in a market. Representative household units (RHUs) may be generated, and the RHUs may be assigned a class for each of the demographic attributes and a quota based on the demographic attributes of a plurality of panelist households. Each of the panelist households may be assigned to one of the RHUs based on at least one panelist classes matching the classes for respective demographic attributes of the RHU, and the number of matching panelist households assigned to each of the RHU may be based on the quota. Panelist viewing data representing viewing events associated with the panelist household may be accessed. A report may be generated with the classes of the RHUs and the panelist viewing data of the assigned panelist households.

An electronic apparatus is provided. The electronic apparatus includes: a display; and a processor configured to: control the display to display a content based on one mode of a plurality of display modes, receive a user voice in real time while the content is being displayed, identify user's age information corresponding to the received user voice, identify whether or not the one mode is a kids mode when the identified user's age information is less than a threshold value, and change the one mode to the kids mode when it is identified that the one mode is not the kids mode.

A system and method for streaming customized audio is disclosed. The system and method allow for the selection of advertisements based on at least one feature of a listener and insertion of the selected advertisements into a customized digital audio stream subsequently transmitted to a particular listener. In a particular embodiment, the advertisement is provided as a text string which is converted into audio for insertion into customized digital audio stream.
