Articulatory phonetics

Articulatory phonetics is a part of phonetics that focuses on how we physically make speech sounds. It looks at how our mouth, tongue, lips, and other parts work together to produce the sounds we use in language.

When studying articulatory phonetics, we talk about three main things:

 

Place of articulation: This means where in our mouth or throat the sound is made. For example, some sounds are made by touching our lips together (like the sounds /p/ or /m/), while others are made by touching our tongue to the roof of our mouth (like the sounds /t/ or /s/).

 

Manner of articulation: This describes how the airflow is changed or blocked to make the sound. Some sounds are made by completely blocking the air briefly (like the sounds /p/ or /k/), while others are made by only partially blocking the air (like the sounds /s/ or /f/), and some are made without blocking the air at all (like vowels such as /a/ or /i/).

 

Voicing: This refers to whether the vocal cords vibrate when making a sound. Some sounds are made with vibration (like /b/ or /z/), while others are made without vibration (like /p/ or /s/).

 

Researchers use different methods to study articulatory phonetics, such as X-rays, ultrasound, and MRI scans, to see how the mouth and throat move during speech. By understanding how speech sounds are produced, we can analyze different languages, study speech problems, and develop technologies like speech recognition and synthesis systems.

Auditory phonetics

Auditory phonetics is a part of phonetics that focuses on how we hear and understand speech sounds. It studies how sounds are made by speakers, travel through the air, and are then understood by our ears and brain.

Our auditory system is important for understanding speech. When we talk, our mouth and throat make different patterns of air pressure that create sound waves. These sound waves reach the listener's ears and are processed by their auditory system.

Auditory phonetics tries to understand how we perceive speech. It explores how we hear and group different speech sounds, how we tell similar sounds apart, and how we get meaning from the sounds we hear. It also looks at how things like background noise, the speaker's voice, and language patterns affect how we understand speech.

Scientists who study auditory phonetics use different methods to learn about speech perception. They might ask people to do tasks like recognizing sounds or telling them apart. They also use special machines like fMRI and EEG to see how the brain processes speech.

Studying auditory phonetics helps us understand how we hear and understand speech. It has practical uses in fields like speech technology, audiology (hearing health), and learning a second language. Knowing how people hear speech can help us design better speech recognition systems, hearing aids, and ways to teach languages.

Acoustic phonetics

Acoustic phonetics is a part of phonetics that studies the physical aspects of speech sounds. It focuses on analyzing and measuring the sounds we make when we speak. The goal is to understand how different sounds are created, transmitted, and heard.

When we speak, our vocal tract, which includes our lungs, larynx, and other parts involved in producing speech, creates sound waves. These sound waves travel through the air as acoustic signals. Acoustic phonetics examines these signals and studies their properties, like how loud they are, their pitch, how long they last, and their characteristics in terms of frequency.

There are some important ideas and measurements in acoustic phonetics:

 

Amplitude: This refers to the strength or power of a sound wave. It affects how loud a sound is perceived.

 

Frequency: It tells us how many cycles a sound wave completes in a given time. It affects the pitch of a sound. Higher frequencies mean higher-pitched sounds.

 

Spectrogram: It is a picture that shows us how the frequencies of a sound wave change over time. It helps us understand the different parts of a sound and their characteristics.

 

Formants: These are specific frequency areas in the sound wave of a vowel sound. They are important for identifying and distinguishing vowels. The shape of our vocal tract affects these formants.

 

Duration: This tells us how long a sound lasts. It is important for telling apart different speech sounds, especially consonants.

 

Intensity: This refers to the power or energy of a sound wave. It affects how loud a sound is perceived. Intensity is measured in decibels (dB).

 

Acoustic phonetics is essential in many areas of research, like understanding how we produce and hear speech, developing speech recognition technology, studying speech for legal purposes, and helping people learn a second language. By studying the acoustic properties of speech sounds, researchers can learn more about how we make sounds and what influences how we hear them.

Phonetics and Phonology

Phonetics and Phonology are two parts of language study that look at the sounds we make when we speak. Although they are related, they focus on different things.

 

Phonetics looks at the physical properties of sounds, like how we make them, how they travel, and how we hear them. It studies the different ways sounds are made in different languages, such as the movements of our mouth and throat, the air that carries the sounds, and how our ears perceive them. Phonetics also examines the physical features of sounds, like how high or low they are, how loud they are, and how long they last.

 

Phonology, on the other hand, looks at how sounds are organized and used in specific languages. It focuses on the ideas and rules we have in our minds about how sounds work in language. Phonology explores how sounds function and interact in a language to convey meaning and distinguish words. It studies sound patterns, like the unique sounds we use in a language, the rules for combining sounds, and the changes sounds undergo in different situations. Phonology is interested in the structure and organization of sound systems and how they contribute to language meaning and communication.

 

In short, phonetics deals with the physical side of speech sounds, while phonology looks at the abstract organization and patterns of sounds in languages. Both fields are important for understanding and describing the complex nature of human language.

Speech sounds

Phonetics is the study of speech sounds. It looks at how sounds are made, heard, and understood by people. Speech sounds are the small parts that make up words and give them meaning. Phonetics groups these sounds into different categories based on how they are made and what they sound like.

 

Articulatory phonetics studies how speech sounds are produced by our mouth, throat, and other parts of our body. It looks at the movements and positions of our lips, tongue, and vocal cords when making specific sounds. For example, the "p" sound is made by closing our lips and pushing out a burst of air.

 

Acoustic phonetics focuses on the physical properties of speech sounds. It examines the sound waves that are created when we speak, like their loudness, pitch, and length. These properties help us tell the difference between different sounds.

 

Perceptual phonetics studies how we hear and understand speech sounds. It explores how we recognize and group sounds together, and how the context can affect our understanding.

 

Phonetics uses special symbols called the International Phonetic Alphabet (IPA) to represent speech sounds. Each sound has its own symbol or combination of symbols. For example, the symbol for the "p" sound is [p].

 

In simple terms, phonetics helps us study and describe the sounds we make when we talk. It helps us understand how we produce and interpret speech, which is important for understanding language.

Respiratory system - Lungs

The lungs are important organs in our body that help us breathe and talk. They are like sponges and are located in our chest. When we speak, air comes out from our lungs and travels through our body to make sounds. The lungs give us the power to make the air flow needed for talking.

When we talk, our muscles make the lungs expand and take in air. This makes the air pressure inside the lungs go down, and we breathe in. When we finish talking, the muscles relax, and the lungs go back to their normal size. This makes the air pressure inside the lungs go up, and we breathe out. The air that comes out is changed by other parts of our body, like our throat, vocal cords, and mouth, to make different sounds.

The way we move our tongue, lips, teeth, and the roof of our mouth also helps us make different sounds when we talk. By moving these parts, we can make many different sounds that make up our language.

To put it simply, the lungs are really important for breathing and talking. They work together with other parts of our body to make the air move and create different sounds when we speak.
