PROBLEM TO BE SOLVED: To provide a sound source enhancement learning device for learning sound source enhancement in which sound quality degradation is suppressed.SOLUTION: A sound source enhancement learning device includes: a Wiener filter templating unit 110 for a finite number of Wiener filter templates from a set of frequency domain target sound learning data and frequency domain noise learning data; an action-value function initialization unit 120 for initializing an action-value function; a sound source enhancement unit 130 for applying an appropriate Wiener filter template selected on the basis of a state vector generated from the set of frequency domain target sound learning data and frequency domain noise learning data and a value of the action-value function calculated using Wiener filter template data to a frequency domain observation signal and thereby generating an enhanced target sound; an action-value function update unit 150 for updating the action-value function using an auditory evaluation value calculated from the enhanced target sound; and a convergence determination unit 160 for outputting the action-value function when a prescribed convergence condition is satisfied.SELECTED DRAWING: Figure 3
