Computational Linguistics - IPA and XSampa

Explore English consonants, vowels, and semi vowels, learn that vowels aren’t always five, and review IPA consonants, vowels, and semi vowels.

Compare consonants and vowels by showing how airflow is obstructed by the tongue or teeth to form consonants and phonemes, unlike vowels with unobstructed airflow.

Explore how consonants are produced at different places of articulation, including labial, dental, alveolar, palatal, and glottal, and how the IPA table maps these production sites.

Explore how consonants are produced across places of articulation and the six articulation models—plosives, nasal, trill, fricative, approximate, and lateral approximate—plus implosive consonants.

Learn how phonation distinguishes voiced from voiceless consonants: vibrating vocal cords produce voiced sounds, non-vibrating cords produce voiceless sounds, with IPA examples showing left (voiceless) and right columns.

this lecture explains plosive consonants, detailing three types by labial, alveolar, and filler, with voiceless vs voiced pairs (p/b, t/d, k/g), referencing ipa and xsampa, highlighting six english plosives.

Explore nasal consonants in English and their IPA transcription. Understand how nasals interact with following plosives and transcription rules before k and g.

Explore the English trill phoneme, the only trill sound, and how it is represented in IPA and XSampa, including the name you use in dictionaries.

Explore the nine English fricative phonemes, defined as turbulent airflow, including voiceless and voiced sounds across dental, alveolar, and glottal categories. Create an IPA-style consonant table focused on English fricatives.

Explore English's sole approximant, the palatal semivowel, described as a palatal voiced sound linked to the J and the w.

Explore the only lateral proximal sound in English, the alveolar and voiced l, represented by the letter l, with examples like liability and tongue placement guiding airflow along the sides.

Explore two consonant combinations in English and the semivowel not listed in the IPA table, illustrated by examples like batch. Eliminate nonessential phonemes to focus on those present in English for transforming IPA to XSampa.

Explore the mapping of English consonants from ipa to x-sampa, reviewing plosives, nasal fricative, and glottal and palatal articulations while noting places of articulation like dental and alveolar.

Explore vowels in section five and how their production depends on tongue position and the form of the lips, including tongue depth and lip shape.

Explore how tone depth positions vowels as front, central, or back. Note that vowels keep airflow open, with e forward, you move forward then back, and o pulls back.

Identify how tongue height shapes vowel production, showing high vowels like e and u raise the tongue and reduce oral space, while low tongue height enables other phonemes.

Explore how lip rounding affects vowel production and how rounded versus unrounded vowels are represented on the vowel chart, highlighting tongue depth and height and lip shape.

Discover the difference between short and long vowels in English, that English has five long vowels, how long vowels are held longer during pronunciation, and representation in symbols section.

Examine how diphthongs blend vowels in English, compare American and British pronunciations, and introduce IPA basics, including semi vowels and vowel representations.

Explore 12 English vowels, distinguishing front, central, and back placements, the close–open distinction, and schwa. Learn to map IPA vowels to x-sampa using guidelines and preview converting consonants and semivowels.

Map IPA consonants to X-Sampa for English, highlighting keyboard-friendly substitutions using capital letters for non-keyboard symbols. Compare alveolar sounds and note vowel differences.

Transcribe English vowels from IPA to X-Sampa using the course's symbol mappings, including schwa and its upside-down e form. Develop a converter to transform IPA to X-Sampa and back.

Build a Python-based converter to transform between IPA and XSAMPA bidirectionally, using functions and dictionaries to output a word in IPA from XSAMPA or vice versa.

Create a dictionary mapping IPA to X-Sampa to build a converter, covering bilabials, plosives, nasals, fricatives, vowels, punctuation, and spaces, enabling IPA and X-Sampa translation.

Learn to build Python functions that convert IPA sequences to XSampa by mapping IPA characters through a dictionary, iterating over user input, and joining results into an XSampa string.

Define a function to convert X-Sampa to IPA using a dictionary and the get method for user input. Prepare to transform IPA back to example when needed.

Explore how to capture user intention by prompting for a numeric option to convert between IPA and example IPA, building a simple interactive converter.

Develop a bidirectional IPA to example converter driven by user input, using prompts and dedicated functions to transform IPA to example and back, with a dictionary-based lookup.
