moving from pybtex to bibtextparser, fixed major regressions.

* only bibtex format is supported
* all tests except test_repo.py and edit test pass
* edit and update commands were not updated
* removed --format argument from export, only bibtex is supported.

We investigate one mechanism among many that may contribute to this process, a key factor being the sensitivity of learners to the statistical distribution of linguistic elements. As well as being necessary for learning word meanings, the acquisition of anchor word forms facilitates the segmentation of an acoustic stream through other mechanisms. In our experiments some salient one-syllable word forms are learnt by a humanoid robot in real-time interactions with naive participants. Words emerge from random syllabic babble through a learning process based on a dialogue between the robot and the human participant, whose speech is perceived by the robot as a stream of phonemes. Numerous ways of representing the speech as syllabic segments are possible. Furthermore, the pronunciation of many words in spontaneous speech is variable. However, in line with research elsewhere, we observe that salient content words are more likely than function words to have consistent canonical representations; thus their relative frequency increases, as does their influence on the learner. Variable pronunciation may contribute to early word form acquisition. The importance of contingent interaction in real-time between teacher and learner is reflected by a reinforcement process, with variable success. The examination of individual cases may be more informative than group results. Nevertheless, word forms are usually produced by the robot after a few minutes of dialogue, employing a simple, real-time, frequency dependent mechanism. This work shows the potential of human-robot interaction systems in studies of the dynamics of early language acquisition.</p>},

-            of anchor word forms facilitates the segmentation of an acoustic stream
-            through other mechanisms. In our experiments some salient one-syllable
-            word forms are learnt by a humanoid robot in real-time interactions with
-            naive participants. Words emerge from random syllabic babble through a
-            learning process based on a dialogue between the robot and the human participant,
-            whose speech is perceived by the robot as a stream of phonemes. Numerous
-            ways of representing the speech as syllabic segments are possible. Furthermore,
-            the pronunciation of many words in spontaneous speech is variable. However,
-            in line with research elsewhere, we observe that salient content words
-            are more likely than function words to have consistent canonical representations;
-            thus their relative frequency increases, as does their influence on the
-            learner. Variable pronunciation may contribute to early word form acquisition.
-            The importance of contingent interaction in real-time between teacher
-            and learner is reflected by a reinforcement process, with variable success.
-            The examination of individual cases may be more informative than group
-            results. Nevertheless, word forms are usually produced by the robot after
-            a few minutes of dialogue, employing a simple, real-time, frequency dependent
-            mechanism. This work shows the potential of human-robot interaction systems
-            in studies of the dynamics of early language acquisition.</p>
