Validating database query results

Despite its complexity, the TIMIT corpus only contains two fundamental data types, namely lexicons and texts.As we saw in 2., most lexical resources can be represented using a record structure, i.e. A lexical resource could be a conventional dictionary or comparative wordlist, as illustrated.Structured collections of annotated linguistic data are essential in most areas of NLP, however, we still face many obstacles in using them.

Finally, TIMIT includes demographic data about the speakers, permitting fine-grained study of vocal, social, and gender characteristics.

TIMIT illustrates several key features of corpus design.

First, the corpus contains two layers of annotation, at the phonetic and orthographic levels.

In general, a text or speech corpus may be annotated at many different linguistic levels, including morphological, syntactic, and discourse levels.

It could also be a phrasal lexicon, where the key field is a phrase rather than a single word.

A thesaurus also consists of record-structured data, where we look up entries via non-key fields that correspond to topics.Like the Brown Corpus, which displays a balanced selection of text genres and sources, TIMIT includes a balanced selection of dialects, speakers, and materials.For each of eight dialect regions, 50 male and female speakers having a range of ages and educational backgrounds each read ten carefully chosen sentences.: Structure of the Published TIMIT Corpus: The CD-ROM contains doc, train, and test directories at the top level; the train and test directories both have 8 sub-directories, one per dialect region; each of these contains further subdirectories, one per speaker; the contents of the directory for female speaker A fourth feature of TIMIT is the hierarchical structure of the corpus.With 4 files per sentence, and 10 sentences for each of 500 speakers, there are 20,000 files.Moreover, notice that all of the data types included in the TIMIT corpus fall into the two basic categories of lexicon and text, which we will discuss below.
