Study Notes
Speech Technology
- Speech and language technology (SLT) uses computational methods to process and understand human speech and written language.
- SLT comprises numerous aspects of human-computer interaction, including speech & voice recognition, predictive text, voice-command interfaces, spell & grammar checkers, document summarization, and text-to-speech synthesis.
- SLT relies on automated parsing and analysis of human language.
- SLT comprises two subfields: speech processing and natural language processing (NLP).
Forensic Phonetics
- Forensic phonetics is the application of knowledge, theories, and methods of general phonetics to practical tasks related to police work or legal proceedings.
- It includes developing new forensic-phonetic knowledge, theories, and methods.
- Experts in forensic phonetics often use a combination of software, expertise, and statistical approaches in their analyses.
- Computer scientists have developed technologies to automate linguistic and phonetic analyses using Artificial Intelligence (AI).
Multimodal Technologies
- Multimodal technologies integrate multiple types of input and output data, such as speech, text, images, and gestures to enhance human-computer interaction.
- Aim to create more natural, accurate, and usable systems.
- Examples of multimodal systems:
- Virtual assistants like Siri and Alexa.
- Interactive language tutoring platforms.
- Speech recognition systems incorporating visual context.
- These technologies are key advancements that create more engaging and natural communication systems.
Speech Processing
- Speech processing is the science of how speech communication works: production by the speaker and understanding by the listener.
- It's also about analyzing and modeling these processes and using those models for technologies that produce and understand speech (synthetic voices, speech recognizers).
- Speech technology is vital for understanding and remediating disordered speech.
- Speech technology intersects various disciplines, particularly linguistics, psychology, acoustics, and engineering.
Core Speech Technologies
- Automatic Speech Recognition (ASR) transcribes speech to text.
- Text-to-Speech (TTS) transforms written text into speech.
- Language Generation translates concepts into words.
- Spoken language understanding (similar to written language parsing).
- Speaker verification and voice print technologies are also fundamental.
Language Processing
- Language processing focuses on computational theories of grammar and meaning.
- It provides access to fundamentals of linguistics as a science and an engineering discipline.
- It's concerned with language as a medium for thought and communication.
- It's used in tools like predictive text, automated personal assistants, web search, and sentiment analysis.
Key Technologies in Speech and Language Technology
- ASR: covers its workings and major systems like Google Speech and DeepSpeech.
- TTS: outlines its pipeline and popular engines like Amazon Polly and Festival.
Real-World Use Cases
- Speech assistants (Siri, Alexa, Google Assistant).
- Real-time transcription (Otter.ai).
- Machine translation (DeepL, Google Translate).
- Healthcare and accessibility applications.
Course Content
- Course topics:
- Introduction to Forensic Phonetics and Linguistics Applications.
- Speaker Identification and Verification, Voice print, and the Document Examiner (using Audacity software).
- Challenges of Spoken Arabic Processing.
- Speech Synthesis (using Praat).
- Arabic Text-to-Speech.
- Speech Recognition System (using Google Cloud).
- Data in Forensic Phonetics.
Pre-Reading for Next Lecture
- Read and summarize the chapter: Sinha.S (2015): Forensic Linguistics and Forensic Phonetics: An Introduction, International Journal of Interdisciplinary and Multidisciplinary Studies (IJIMS), 2015, Vol 2, No.6, 153-157.
