Abstract
A method and system for teaching non-lexical speech effects includes delexicalizing a first speech segment to provide a first prosodic speech signal and data indicative of the first prosodic speech signal is stored in a computer memory. The first speech segment is audibly played to a language student and the student is prompted to recite the speech segment. The speech uttered by the student in response to the prompt, is recorded.

A method, comprising:
- delexicalizing a speech segment to generate a first prosodic speech signal;
- encoding the first prosodic speech signal to generate a musically encoded prosodic speech signal;
- storing data indicative of the musically encoded prosodic speech signal in a computer memory;
- audibly playing the musically encoded prosodic speech signal to a language student;
- prompting, in response to the audibly playing, the student to recite the speech segment from which the musically encoded prosodic speech signal originated;
- recording audible speech uttered by the student in response to the prompt;
- delexicalizing the audible speech to generate a second prosodic speech signal;
- calculating at least one error signal based on a difference between:
- a difference between a duration of a first syllable in the first prosodic speech signal and a duration of a second syllable in the first prosodic speech signal, the first syllable in the first prosodic speech signal being non-adjacent to the second syllable in the first prosodic speech signal;
- and
- a difference between a duration of a first syllable in the second prosodic speech signal and a duration of a second syllable in the second prosodic speech signal, the first syllable in the second prosodic speech signal being non-adjacent to the second syllable in the second prosodic speech signal.

A method, comprising:
- audibly presenting a non-lexicalized musically encoded phrase in a target language to a student;
- receiving, at a computer, a lexicalized version of the non-lexicalized musically encoded phrase in the target language from the student;
- comparing, at the computer, non-lexical properties of the non-lexicalized musically encoded phrase with non-lexical properties of the lexicalized version of the non-lexicalized musically encoded phrase to calculate at least one error signal based on a difference between:
- a difference between a duration of a first syllable in the non-lexicalized musically encoded phrase and a duration of a second syllable in the non-lexicalized musically encoded phrase, the first syllable in the non-lexicalized musically encoded phrase being non-adjacent to the second syllable in the non-lexicalized musically encoded phrase;
- and
- a difference between a duration of a first syllable in the lexicalized version of the non-lexicalized musically encoded phrase and a duration of a second syllable in the lexicalized version of the non-lexicalized musically encoded phrase, the first syllable in the lexicalized version of the non-lexicalized musically encoded phrase being non-adjacent to the second syllable in the lexicalized version of the non-lexicalized musically encoded phrase;
- and
- adjusting a future lesson for the student based upon the error signal.

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to:
- encode a first prosodic speech signal to generate a musically encoded first prosodic speech signal by mapping each syllable of the first prosodic speech signal to a musical note;
- store the musically encoded first prosodic speech signal;
- audibly play the musically encoded first prosodic speech signal to a language student;
- prompt the student to recite the speech segment from which the musically encoded first prosodic speech signal originated;
- record an utterance from the language student in response to the prompt;
- delexicalize the utterance to generate a second prosodic speech signal;
- and
- calculate at least one error signal based on a difference between:
- a difference between a duration of a first syllable in the first prosodic speech signal and a duration of a second syllable in the first prosodic speech signal, the first syllable in the first prosodic speech signal being non-adjacent to the second syllable in the first prosodic speech signal;
- and
- a difference between a duration of a first syllable in the second prosodic speech signal and a duration of a second syllable in the second prosodic speech signal, the first syllable in the second prosodic speech signal being non-adjacent to the second syllable in the second prosodic speech signal.
