Because ChromoLang uses special codes and because the transcripts are not linked to the video, the full collection of original transcripts is available in this zip file The files in the browsable database were created through ASR and are mostly just useful for playing back video with an emphasis on the parents' speech. Correct encoding of the details of the speech is in the ChromoTrans files. Privacy considerations require that access to the video requires that permission be granted by the data contributors.

Project Description

The acronym CHROMOLANG stands for CHROMOsomopathies and LANGuage. The corpus collects conversations among 8 Spanish children (age range 3;4 – 11;6) with rare chromosomal disorders and their close relatives and/or speech therapists in naturalistic environments. It consists of 21 transcripts with their corresponding videos, distributed as follows:

1JCL: 1 transcript of a child (male, 5;8. years old) bearing a microduplication in 1q21.1
2JEV: 1 transcript of a child (male, 11;6. years old) bearing a microdeletion in 8p23.1 and a microduplication in 9p24.3
3ACS: 3 transcripts of a child (female, 9;9.; 10;2., and 10;3. years old) bearing a microduplication in 1q42.3q43
4DAR: 5 transcripts of a child (male, 6;4. years old) bearing a microdeletion in 14q13.1
5BRL: 2 transcripts of a child (female, 7;11., and 9;10. years old) bearing a microdeletion in 2p16.3
6GVA: 2 transcripts of a child (male, 11;2. years old) bearing a microdeletion in 7q11.23
7ECC: 4 transcripts of a child with Xq28 (male, 3;4., and 3;5. years old) duplication syndrome
8JGR: 3 transcripts of a child (male, 6;9., and 6;11. years old) bearing a microdeletion in 16p11.2

The clinical history of each informant, along with the results of extensive molecular and cytogenetic analyses, and of multiple linguistic, cognitive and behavioral standardized assessments can be found in the papers linked to each of the transcripts in the previous section. We cannot provide the same information for DAR, GVA, and ECC, as these studies are still pending publication.

The total duration of the conversations is about two hours, with an approximate average of 15 minutes per informant. The data were collected as part of the research project led by Antonio Benítez-Burraco with funding from the Spanish Ministry with competences in Science (MINECO) (REF: FFI2016-78034-C2-2-P) within the State Plan for the Promotion of Scientific and Technical Research of Excellence. We studied children with various low-prevalence chromosomal disorders from a genetic, neuropsychological, and communicative perspective, with the aim of contributing to the description of the cognitive, linguistic, and communicative impairments associated with their genetic abnormalities.

Data collection protocol

Dr. Mª Salud Jiménez Romero, a speech therapist with the CHROMOLANG project, contacted the participants. Some of the speech samples were collected at the clinic, always in the presence of the participants' parents and siblings, and when the children were accustomed to the speech therapist's presence. In some cases, the children's parents were asked to video record them during conversations in familiar settings with family members. A detailed description of the methodological protocol used to carry out these case studies can be found in the publications cited above.

Codes

The codes used in the main and dependent tiers of the transcripts are summarized and exemplified in this table The first four codes in the table refer to phonetic phenomena characteristic of the dialectal varieties of Andalusian Spanish. The majority of the informants in the ChromoLang corpus are children from different regions of Andalusia, making it essential to consider their dialectal characteristics. To this end, it is crucial to pay attention to how their parents and close relatives produce certain phonemes (mainly /s/, /l/, /ɾ/, /r/) that tend to disappear, be aspirated, or assimilate in the post-nuclear syllable margin, depending on the phonetic context, and whose omission may or may not lead to an increase in the opening of the preceding vowel. When the informant or their family members produce any of these phonetic phenomena [ħ, pħ, tħ, cħ, pp, tt, l-l, A, E, O] we additionally code the word with the symbol @d.

Ethics approval for this research was granted by the Ethics Committee of the “Reina Sofía” Hospital (Córdoba, Andalucía, Spain). All participants' legal guardians gave their written informed consent for the collection and use of their data for research purposes, provided their anonymity was preserved. Therefore, pseudonyms have been used, and we request the utmost discretion in the use of the video files (approved access level).
