Using Speech Technology to Test Theories of Phonetic and Phonological Typology (2024.lrec-main)
Copied to clipboard
| Challenge: | acoustic studies show that obstruents in European Portuguese have different voicing profiles than their Romance relatives. |
| Approach: | They propose to use speech technology to test phonetic typology in European Portuguese . they use acoustic phone models to force align different phone models for obstruents . |
| Outcome: | The proposed method supports previous accounts that European Portuguese is diverging from the traditional voicing system known for Romance languages towards a hybrid system where stops and fricatives are specified for different voicing features. |
The French-Algerian Code-Switching Triggered audio corpus (FACST) (L18-1)
Copied to clipboard
| Challenge: | The French Algerian Code-Switching Triggered corpus is a corpus of spontaneous CS utterances . it is used to support linguistic and phonetic studies in phonetics and prosody . |
| Approach: | They propose to use a triggering protocol to elicit CS in natural conversations . they propose to do data segmentation and annotation in each language . |
| Outcome: | The proposed corpus is based on a code-switching protocol and is well-suited for linguistic and acoustic-phonetic studies. |

| Challenge: | a new study aims to document endangered languages using a speech corpus . linguistic documentation is limited to the phonetic, lexical and syntactic levels . |
| Approach: | They propose to use a speech corpus to document endangered languages in field . they propose to collect 5k speech utterances aligned to French text translations . |
| Outcome: | The proposed language corpus is used to document endangered languages in field linguists . it is multilingual and contains 5k speech utterances aligned to french text translations - the authors show it can be used in a zero-resource task . |
Using a Knowledge Base to Automatically Annotate Speech Corpora and to Identify Sociolinguistic Variation (2022.lrec-1)
Copied to clipboard
| Challenge: | Speech characteristics vary from speaker to speaker due to many factors, including communication context, provenance, age, and social background. |
| Approach: | They propose a method that uses a knowledge base to provide speaker-specific information. |
| Outcome: | The proposed method can be used to enrich existing corpora with speaker-specific information and to correlate with diastratic features. |

| Challenge: | BULB project aims to provide tools to language documentation and description for unwritten languages . language-based technologies are needed to support the collection of data and to provide linguistic documentation for the languages. |
| Approach: | This paper presents multimodal and parallel data collections in Mboshi, as part of the French-German BULB project. |
| Outcome: | The proposed data collection includes pictures and videos documenting social practices, agriculture, wildlife and plants. |
Extracting Linguistic Knowledge from Speech: A Study of Stop Realization in 5 Romance Languages (2022.lrec-1)
Copied to clipboard
| Challenge: | voicing alternation phenomena of stops are a common problem in connected speech . phoneticians and phonologists are interested in analyzing phonetic variation . |
| Approach: | They use forced alignment with pronunciation variants and machine learning techniques to examine voicing alternations of stops in Romance languages. |
| Outcome: | The proposed method enables linguists to use large corpora and speech recognition systems . the results show that voicing alternations occur in all Romance languages . |
