Qs: Vowel Speech Corpus; L2 Lexical Attrition

Editor for this issue: Naomi Fox <foxlinguistlist.org>


We'd like to remind readers that the responses to queries are usually best posted to the individual asking the question. That individual is then strongly encouraged to post a summary to the list. This policy was instituted to help control the huge volume of mail on LINGUIST; so we would appreciate your cooperating with it whenever it seems appropriate. In addition to posting a summary, we'd like to remind people that it is usually a good idea to personally thank those individuals who have taken the trouble to respond to the query. To post to LINGUIST, use our convenient web form at http://linguistlist.org/LL/posttolinguist.html.

Message 1: Speech Corpus for Neural Network Training

Subject: Speech Corpus for Neural Network Training

I am involved in a research project whose goal is to produce a
software system for the control of electronic devices using continuous
variables extracted from human speech. Part of this system will be a
neural network that recognizes various vowels and produces tracks of
pitch and formant frequencies. Training the neural network will
require a large amount of data that we're hoping to get from an
existing corpus, rather than creating it ourselves.

We are looking for a corpus that contains samples of many speakers
producing many vowels (preferably in a less reduced register) that
also contains human-validated pitch and formant (F1, F2, and F3)
tracks and, if possible, bandwidth information. A corpus that
contains more than just vowels is fine, since we can discard sections
of the samples that do not suit our needs.

If anyone knows of a corpus like this, either freely distributed or
requiring a fee, I would like to know how to get ahold of it.

I will post a summary of the replies that I receive. Thanks in
advance for your time.

Message 2: L2 lexical attrition

Subject: L2 lexical attrition

Dear Linguist

I am an EFL graduate student. I have decided to investigate the extent
of L2 lexical attrition in high school students over summer holidays
when they recive no L2 input. As the period of nonuse of/ no exposure
to the L2 is only about 12 weeks, is it possible to consider such a
case as an attrition study? Many thanks in advance.
