PRESENT RESOURCES

• Siemens,

• Nokia

LC-STAR Mandarin lexicon and TC-STAR Mandarin TTS database (1 male voice) for exchange in ECESS.

• AMU

LC-STAR Polish lexicon

7.The actual state of LR specification.

o Settling/Finalization the specification for Text Corpora (Pool Text1, Pool Text2).

o Settling/Finalization the specification for Acoustic data for TTS voices (minimal requirements - Pool Voice2).


Design Principles of the Acoustic Corpora

Size of corpus10 h speech per baseline speaker per language‘Baseline Text Corpus’ is composed by the corpora**Transcribed speech 45 000 words Written text (novels and short stories with short sentences)

27 000 wordsSelected phrases (frequent phrases, triphone sentences, mimic sentences)

18000 words

Minimal requirements acoustic data. Coordinated by University of Munich

LR College Maribor: 9th ECESS meeting

Text corpus specifications (for POS tagging)

Size of corpus:

Expected size of text data: 100K tokens minimum, 100% manually checked

rest (500K-1M) can be done automaticallyDomains:

Mandatory: 20K should be coming from spoken transliterations

Preferred: in line with the TC-STAR text corpora (in line with acoustic data creation)

TC-STAR text corpus as basis for POS tagging (90Kwords)LC-STAR tag set, or comparable, but tag set in lexicon and

tagged text corpus must match


Discussion

POS tagging • Size of text, domains• Tokenization problems• POS tagging sets• Format of POS tagging • Validation

9. Discussion. General issues.

o ECESS LR specification documents (public page)

o LSPs specifications (internal page)

o Splitting LR

o LR distribution (internal page)

o LR exchanging agreement

ECESS LR specification documents (public page, internal page)

The language independent specification is public and should be accessible from the public ECESS web-page.

The language specific data (Language Specific Peculiarities);

the LSP could be extended to contain all the 'contact information') is part of the LR dedicated for a pool. The LSPs have to be approved by the LR-college. The LSPs are located in the internal webpage of ECESS (College LR).

A new public 'ECESS' specification document.

(different LC-STAR ,TC_StAR documents together, ECESS specification

LR papers, publication


• Splitting LR

SIE suggests to split the data in the lexicon pool to 'lexicon for common words' (which we will deliver for UK) and 'lexicon for proper names'.

Partners interested only in parts of the lexica could then choose what they want to deliver and exchange.

Advantage: some partners may only want to deliver/get certain parts of a particular language; production costs for the different parts are more comparable.


o LR distribution (internal page) o LR exchanging agreement

LR-agreement: within the college 'Tools‘ Uni. Maribor acts as a distributor of tools needed for evaluation.


• 10. Discussion. Further directions of LR College

o Promotion of ECESS LRo Extension of LR collection. New types of Pools (eg.

acoustic databases for speaker characterization, emotional databases, special databases with pathological voices/speech) depending on interests and needs of Ecess.
