Speech Technologies
1. Text-to-speech (TTS)
2. Automatic speech recognition (ASR) - speech-to-text

Text-to-Speech• Reading back emails, messages, posts, notes
• Books read to the user (Kindle)
• Voice command and control
• Audio dictionaries
• Accessibility and inclusivity
• MALL and literacy (Roux et al, 2010)

Mobile-Assisted Language Learning
• Mobile-Assisted Language Learning– reading and speaking– dictation– communication, facilitation and feedback– pronunciation practice (speech verification)– speech analysis and language learning software
(Godwin-Jones, 2009)– vocabulary practice (Kumar et al, 2012)
• Phonetics and phonology (Linguistics)– speech signal processing (DSP)– patterns recognition (AI)

Other Advantages
• Voice-based tools - assistive technology• Individualized attention • Enforced feedback• Learner-centered: own pace, preferences,
autonomy• Repetition and rehearsal

Limitations
• Limited success with spontaneous, natural foreign accented speech
• Type of mobile device• Usability: tools• Usability: context• Usability: data consumption
