The method includes presenting a relaxing audio segment that induces a relaxed receptive state in the language speaker, and then presenting a training audio segment that presents at least one model speaker pronouncing at least portions of speech in accordance with a target accent, while presenting the repeating beat frequency pattern. The relaxing audio segment can include instructions to promote relaxation in the listener's native language or in the target language. The method thereby enables learning pronunciations that are deeply rooted in the subconscious mind, so they sound natural and effortless when used. The method can be synergistically combined with more conventional methods of language learning to great benefit. ## Claims ### Claim 1 A method for changing accent in a spoken language of a listener, the method comprising: presenting an audio segment configured to induce relaxation in the listener; presenting a training audio segment after the audio segment configured to induce relaxation, the training audio segment being configured to expose the listener to at least one model speaker pronouncing words and phrases in a target language in accordance with a target accent; and presenting a brainwave entrainment audio segment during at least the training audio segment, the brainwave entrainment audio segment being configured to induce alpha brainwave frequencies in the brain of the listener; and the brainwave entrainment audio segment includes a sequence of beat frequencies that vary in accordance with a repeating smoothed downward-sloping zig-zag pattern. ### Claim 2 (depends on 1) The method of claim 1, wherein the brainwave entrainment audio segment is presented during both the audio segment configured to induce relaxation and the training audio segment. ### Claim 3 (depends on 1) The method of claim 1, wherein the brainwave entrainment audio segment includes a sequence of beat frequencies that vary in accordance with a repeating smoothed downward-sloping zig-zag pattern, including: a maximum starting frequency value no more than 12.5 Hz; a first decreasing segment that decreases from the maximum starting frequency until reaching a first local minimum frequency; a first increasing segment that increases from the first local minimum frequency until it reaches a first local maximum frequency that is less than the maximum starting frequency; a second decreasing segment that decreases from the first local maximum frequency until reaching a second local minimum frequency; a second increasing segment that increases from the second local minimum frequency until it reaches a second local maximum frequency that is less than the first local maximum frequency; and a third decreasing segment that decreases from the second local maximum frequency until reaching a minimum ending frequency of no less than 7.5 Hz. ### Claim 4 (depends on 1) The method of claim 1, wherein the audio segment configured to induce relaxation includes: a guided imagery relaxation segment configured to guide the listener through imagery and suggestions to relax every part of a body of the listener. ### Claim 5 (depends on 1) The method of claim 1, wherein the audio segment configured to induce relaxation includes instructions to induce relaxation. ### Claim 6 (depends on 5) The method of claim 5, wherein the instructions to induce relaxation are not in the target language of the target accent. ### Claim 7 (depends on 5) The method of claim 5 wherein the instructions to induce relaxation are in the target language of the target accent. ### Claim 8 (depends on 1) The method of claim 1, further including: identifying component sounds of the target accent. ### Claim 9 (depends on 1) The method of claim 1, further including: rehearsing component sounds needed to pronounce the target accent.
