DFKI OT Data

Speech database for the OT Turkish TTS voices in MaryTTS.

Data format

Audio

The audio data is provided in the losslessly compressed FLAC format, which can be played by a myriad of software, including Praat. The speaker was recorded at a 44.1 kHz sampling rate, 16 bits per sample, in mono. No filters of any sort have been applied to this raw data.

Phonetic segmentation

Annotations are provided as a single YAML file. It contains a list of utterances, each of which consists of

• a prompt code (file basename),
• the utterance text,
• the recording date,
• utterance start and end times (in seconds) in the FLAC file,
• the phonetic segments (obtained using the eHMM tool from FestVox 2.1), each of which has
  • a label (based on SAMPA, _ denotes silence), and
  • its duration (in seconds)

For example,

- prompt: ot0798
  text: Resim ticaretine başladı.
  date: 2009-07-10T07:32:17Z
  start: 4553.4053741500
  end: 4556.6553741500
  segments:
  - { lab: _, dur: 0.324969 }
  - { lab: r, dur: 0.1 }
  - { lab: e, dur: 0.1 }
  - { lab: s, dur: 0.135 }
