C-ORAL-ROM

Essential information

Text lenght

In the informal section:

• Short texts: at least 64 texts of around 1500 words each. Up to 20% of this part may be constituted by texts of different lengths.
  
  
• Long texts: from 8 to 10 texts of around 4500 words each.

In the formal section, the text length is defined according to the following rules:

• For Formal in natural context: 2 or 3 samples for each domain of 3000 words average.
  
  
• For Media: 2 or 3 samples for each domain. 3000 words average. Only short samples for Weather forecasting and News.
  
  
• For Telephone: text length not defined (by preference 1500 words upper limit, no lower limit). The Phone to call services and/or human-machine interactions domain should contain 10,000 words. This domain is not present in the Portuguese corpus.

The corpus design matrix has been approximated in each language collection as in the following table:

Acoustic quality

C-ORAL-ROM is oriented towards the collection of corpora in natural environment, despite the fact that this necessarily causes a lower acoustic quality of the resource. Moreover, C-ORAL-ROM has exploited, in the frame of a new multilingual work, the rich contents of the archives set up by the providers during years of research on spoken languages; therefore the acoustic quality and the recording conditions of the resource are variable.

The following are the requirements for the acoustic format and for the recording apparatus:

• Format: mono wav files (Windows PCM), Sampling frequency: 22050Hz, 16 bit.
  
  
• Recording and storing process for old Analogue recordings: directly derived in wav files (20.050 hz 16 bit) from the original analogue tapes through a standard sound card (Sound Blaster live or compatible) with a professional sound editor, Cool Edit 2000 ®.
  
  
• Recording and storing process for new recordings:
  
  
  1. dialogues: stereo DAT or minidisk recording (44.100Hz) with unidirectional Micro-phones, converted into mono .wav files (Windows PCM, 22050Hz, 16 bit) via SPDIF port of a standard sound card (Sound Blaster live or compatible) with a professional sound editor.
     
     
  2. conversations with more than two participants: mono DAT or minidisk recording with cardioids or omni-directional microphone converted into mono .wav files via SPDIF port of a standard sound card (Sound Blaster live or compatible) with a professional sound editor.

The speech files of the acoustic database are defined on a quality scale (recording, volume, voice overlapping and noise). The quality scale extends from the highest level of clarity of the voice signal to low levels of acoustic quality.

1. Digital recordings with DAT or minidisk apparatus and unidirectional microphones or analogue recording of very high quality.
   
   
2. Digital recording with poorer microphone response or analogue recordings with:
   
   
   • Good microphone response
   • Low background noise
   • Low percentage of overlapped utterances
   • F0 computing possible in most of the file
   
   
   
3. Low quality analogue recordings with:
   
   
   • Poor microphone response
   • Background noise
   • Average percentage of overlapped utterances
   • F0 computing possible in many parts of the files

The quality is gauged spectrographically. Sessions in which F0 analysis is not significant are excluded from sampling. The acoustic quality of each recording and the most relevant data on the recording condition are always recorded in the metadata of each text.

Speech and label files

For each spontaneous speech recording session, the following is delivered into folders of the multimedia corpus.

1. Speech files: uncompressed .WAV files (Windows PCM: 22,050 hz; 16 bit).
2. Transcripts in CHAT format enriched by the annotation of terminal and non terminal prosodic breaks and the alignment information, in TXT files.
3. The text-to-speech alignment files: XML file in WIN PITCH CORPUS format.
4. DTD of the WinPitchCorpus alignment format.

Speech files and transcription files are in one to one correspondence. The following is the general table of the C-ORAL-ROM multimedia corpus:

	wavfiles	GB	Duration	Utterances	Words in txt files
French	206	3,77	26.21.43	19546	256271
Italian	204	5,19	36.16.10	40402	311592
Portuguese	152	4,43	29.43.42	38855	317920
Spanish	210	4,56	31.06.00	35588	335471

For each session, the following files are also delivered:

1. The transcription of each session in CHAT format in .TXT files (without the alignment information).
2. The C-ORAL-ROM transcription of each session in .XML files.
3. DTD of the C-ORAL-ROM .XML format.
4. Metadata in CHAT format.
5. Metadata in IMDI format.
6. The C-ORAL-ROM transcription each session with Part of Speech annotation and Lemma annotation for each form in .TXT files.
7. Tag set adopted in .TXT files.
8. Frequency lists of lemmas and Frequency lists of forms in TXT files.
9. Measurements of the Language values recorded in each text: in the Excel files "measurements_language.xls".
10. Line diagrams presenting the trend observed with regard to the standard text variation parameters along the corpus structure's nodes, in the Excel file "Multilingual graphics.xls".
