International Decade of Indigenous Languages

• 2022-2032
• indigenous language - native to a region
• tagalog - indigenous language
• cebuano, hiligaynon, etc. - are not dialects
• language vs dialect
  • dialect: variety of a language
• conyo is a socialect
• idiolect a smaller group of individuals
• gayspeak is a socialect
• bulacan variety of tagalog is a dialect; dialects are varieties of a language
  

what is a similarity matrix?

• tells you how similar and how dissimilar two indices (?) are
  

we're also going to produce a cluster

• once we have a word list, we apply clustering algorithms

Learning Plan

Pag-aaral ng wika

when we deal with languages we deal with:

• phonology: sounds
• morphology: affixes
• syntax
• semantics: grammar
• discourse and dialogue

Phonology

the science of (speech) sounds

if you're interested..

• ronald pascual - goat for audio processing in dlsu
• jocelyn cu - empathic computing, speech sounds like laughter
• thomas tiam-lee - advisee working on speech recognition

Ilan ang vowels sa Tagalog?

• pre-hispanic period: 3 vowels via baybayin system
• that's why there are only 3 vowel sounds in the tagalog language - that's why there are several spelling variants in the language today

but in modern tagalog:
slowly pronounce: a, e, i, o u, basa, biik, lulu

• guide questions: nasaan ang dila? mas malapit sa baba o sa taas ng bibig? paabante o paurong?
  • touching the palate (above)? or touching oral cavity (below)?

kambal patinig

tongue:
a is usually downward
e is usually closer
u is moving towards

Formants

• tagalog vowels: a, e, i, o, u
• F1 refers to the tongue location (closer to palette or oral cavity)
• F2 refers to the tongue
• in terms of phonology, there are more foreign experts working on tagalog more than local experts

you can check vowel space in other languages

Activity 2

In Praat:

• waveform: visualization of the voice
• spectrogram:
• duration

• monotonic view in praat (most are flat)

• open > open from file > week 1 audio in Praat

• (zoom in) by pressing "in" on bottom left
  
  

• intensity: loudness/decibels

recording sound

• praat objects window > record mono (not stereo)
• mono: sound on left is the same on the right
• stereo: different

advanced:

praat objects > annotate > textgrid (need to download)

praat objects > query

if you want to get something from the entire file like minimum, maximum, etc.

thesis topics

• spectrogram
• speech generation: if i put a sad speech in tagalog, how can i make it happy?
• what is the emotion of the speaker from timestamp 1 to 4?
