SpeechArticulationTrainer is a mobile app (as well as a program for laptops and desktops) for the visualization of speech articulation movements and gesture scores of monosyllables.
The app is available as light version in AppStore and GooglePlay (prompt: SpeechArticulationTrainer)

General introduction to older version 3.0, available as software for PCs and MacBooks (see also www.speechtrainer.de):

• SpeechArticulationTrainer 3.0 Introduction
  
• SpeechArticulationTrainer 3.0 Vowels (static)
  
• SpeechArticulationTrainer 3.0 Consonants (static)
  
• SpeechArticulationTrainer 3.0 Consonants (static, coarticulation)
  
• SpeechArticulationTrainer 3.0 Consonants (dynamic, CV-syllables)

• SpeechArticulationTrainer 3.0 Words
  
• SpeechArticulationTrainer 3.0 My Words (generate your own words and word lists)
  
• SpeechArticulationTrainer 3.0 My Lists (load and use in parallel up to nine word lists)
  

The articulatory model:

• SpeTra 3.0: Articulatory model: consonantal parameters: aperture
  
• SpeTra 3.0: Articulatory model: vocalic parameters: high-low, front-back, rounding
  
• SpeTra 3.0: Articulatory model: velum and glottis
  
• SpeTra 3.0: Articulatory model: consonants: manner of articulation: plosives, fricatives. lateral
  

Gestures (vocal tract actions) and gesture score:

• SpeTra 3.0: Introduction to a gesture score and to gestures (example "ba")
  
• SpeTra 3.0: Introduction to a gesture score and to articulatory parameters (example "bo")
  
• SpeTra 3.0: gesture score of CV-syllables: voiced and voiceless plosives
  
• SpeTra 3.0: gesture score of CV-syllables: voiced and voiceless fricatives
  
• SpeTra 3.0: gesture score of CV-syllables: nasals and liquids
  

Coarticulation with gestures (vocal tract actions) and gesture score:

• SpeTra 3.0: CV-Coarticulation, syllable "ba" versus "bi", coarticulation on consonants
  
• SpeTra 3.0: CVC-Coarticulation, syllable "pak" versus "kap", coarticulation on vowels
  

Adding audios to SpeTra and synchronizing audios with SpeTra-model-based articulatory movements:

• SpeTra 3.0: activating audios in menu: words
  
• SpeTra 3.0: adding audios in menu: my lists
  
• SpeTra 3.0: generating .wav-files (and .sound-files) using PRAAT
  
• SpeTra 3.0: synchronizing articulation with audios in menu: words (example CVC "piep")
  
• SpeTra 3.0: synchronizing articulation with audios in menu: words (example CVC "Beil")
  
• SpeTra 3.0: synchronizing articulation with audios in menu: words (example CVCC "Matsch")
