The Basics of Speech Sounds

Defining ‘Place of Articulation’

At the heart of speech sound production is the concept of ‘place of articulation.’ This term refers to the specific part of the vocal tract where airflow is restricted or altered to produce different sounds. The vocal tract consists of various anatomical structures, including the lips, teeth, tongue, alveolar ridge, hard and soft palate, and glottis. By manipulating these structures, we can create a wide range of sounds, each unique to certain languages and dialects.

For more information on speech and language milestones, check out our detailed guide.

How Speech Sounds are Produced

The production of speech sounds is a coordinated effort involving various parts of the vocal tract. When we speak, air from the lungs is pushed out and its flow is shaped by the tongue, lips, and other parts of the mouth and throat. Depending on where this airflow is constricted or modified, different sounds emerge. These sounds are broadly categorized into vowels and consonants, with consonants further classified based on the place of articulation.

For example, when the airflow is obstructed by both lips (a bilabial articulation), it produces sounds like /b/ and /p/. If the tongue touches the teeth (dental articulation), we get sounds like /θ/ in “think.” The complexity and variety of these sounds form the foundation of spoken language, enabling us to communicate a vast array of emotions, intentions, and information.

Bilabial Sounds

Exploring Bilabial Articulation

Bilabial sounds are a fundamental aspect of human speech, characterized by the use of both lips in their articulation. These sounds are produced when the airflow is obstructed by the closure or near-closure of the lips. This category includes some of the first sounds made by infants, highlighting their natural and intuitive place in language development.

In linguistic terms, bilabial sounds are versatile, occurring in numerous languages worldwide. They include both voiced and voiceless consonants, depending on whether the vocal cords vibrate during the articulation.

Discover more about what to expect in speech and language development at these ages by reading about 2 to 3-year milestones and 3 to 4-year milestones.

Examples of Bilabial Sounds

Bilabial consonants are prevalent in everyday language and include sounds such as:

• /p/ as in “pat”: This is a voiceless bilabial plosive, where the sound is produced by releasing a burst of air after the lips part.
• /b/ as in “bat”: A voiced counterpart to /p/, /b/ involves the vibration of the vocal cords while the lips briefly close and then open.
• /m/ as in “mat”: This is a bilabial nasal, where the air escapes through the nose while the lips are closed, and it is voiced.

These sounds illustrate the varied use of bilabial articulation in language, demonstrating its importance in speech.

Labiodental Sounds

Understanding Labiodental Articulation

Labiodental sounds are articulated with the involvement of both the lower lip and the upper front teeth. This type of articulation is characterized by the lower lip making contact with the upper teeth, creating a distinctive sound quality. These sounds are common across many languages and are essential for clarity in speech.

Labiodental sounds offer a contrast to bilabial sounds, as they involve a different part of the mouth, demonstrating the diversity in how humans produce speech sounds.

Examples of Labiodental Sounds

Common labiodental consonants include:

• /f/ as in “fat”: This is a voiceless labiodental fricative produced by forcing air through the narrow gap between the lower lip and upper teeth, creating friction.
• /v/ as in “vat”: The voiced counterpart to /f/, /v/ involves the same positioning but with the addition of vocal cord vibration.

These sounds are essential in many languages for differentiating words and conveying precise meanings.

Dental Sounds

The Nature of Dental Sounds

Dental sounds are a distinctive group of consonants produced by the tongue making contact with the upper teeth. These sounds are termed “dental” due to this direct involvement of the teeth in their articulation. The precise nature of this contact – whether the tongue touches the teeth directly or is positioned close to them – can create subtle variations in sound.

In many languages, dental sounds contribute significantly to phonetic richness and are crucial for clear communication. They often serve to distinguish words that would otherwise sound identical.

Examples of Dental Sounds

Some common dental consonants include:

• /θ/ as in “thin”: This is a voiceless dental fricative, created by the tongue lightly touching the upper front teeth and air passing through the gap, producing a soft hissing sound.
• /ð/ as in “this”: The voiced counterpart to /θ/, /ð/ is produced similarly but with the addition of vocal cord vibration.

These examples illustrate how dental sounds are integral to many languages, adding nuance and precision to speech.

Alveolar Sounds

Exploring Alveolar Articulation

Alveolar sounds are among the most common consonants in many languages. These sounds are produced by the tongue making contact with or coming close to, the alveolar ridge – the small ridge located just behind the upper front teeth. The variety and frequency of alveolar sounds in languages worldwide highlight their importance in human speech.

Examples of Alveolar Sounds

Key alveolar consonants include:

• /t/ as in “top”: This is a voiceless alveolar stop, where the sound is produced by the tongue briefly blocking airflow at the alveolar ridge and then releasing it.
• /d/ as in “dog”: The voiced counterpart to /t/, /d/ involves similar tongue placement but with vocal cord vibration.
• /s/ as in “sat”: A voiceless alveolar fricative produced by positioning the tongue close to the alveolar ridge, creating a narrow channel through which air passes with a hissing sound.
• /z/ as in “zoo”: The voiced version of /s/, where the tongue and alveolar ridge positioning are the same, but with vocal cord vibration.
• /n/ as in “nap”: An alveolar nasal sound made with the tongue pressed against the alveolar ridge while air passes through the nose.
• /l/ as in “lap”: Known as an alveolar lateral approximant, it is produced by allowing air to flow around the sides of the tongue while it touches the alveolar ridge.

These sounds demonstrate the diversity and utility of alveolar articulation in forming words and conveying meaning.

Lingua-Palatal Sounds

Understanding Lingua-Palatal Articulation

Lingua-palatal sounds, commonly known as palatal sounds, are produced by the front part of the tongue coming into contact with or approaching the hard palate. This area is the bony part of the roof of the mouth, located towards the front, just behind the alveolar ridge. The distinctive feature of these sounds lies in their ‘palatal’ quality, where the tongue’s movement towards the hard palate plays a crucial role in sound production.

Palatal sounds are prevalent in many languages and add a rich layer of phonetic diversity to speech.

Examples of Lingua-Palatal Sounds

Key examples of lingua-palatal consonants include:

• /ʃ/ as in “shy”: This is a voiceless lingua-palatal fricative. It is produced by positioning the front part of the tongue close to the hard palate, creating a narrow channel for air to pass through, resulting in a characteristic hissing sound.
• /ʒ/ as in “measure”: A voiced counterpart to /ʃ/, /ʒ/ involves similar tongue placement but with vocal cord vibration.
• /j/ as in “yes”: This sound is a voiced palatal approximant, where the front part of the tongue is raised towards the hard palate but not as close as in /ʃ/ or /ʒ/, allowing the vocalized air to pass through more freely.

These examples underscore the importance of precise tongue and palate coordination in producing distinct lingua-palatal sounds.

Alveo-Palatal Sounds

The Nature of Alveo-Palatal Sounds

Alveo-palatal sounds, also known as post-alveolar sounds, are articulated by the tongue making contact with or moving towards the area between the alveolar ridge and the hard palate. These sounds represent a blend of alveolar and palatal articulations, creating unique and distinct consonants in speech.

These sounds are integral to many languages and offer a fascinating insight into the versatility of human speech production.

Examples of Alveo-Palatal Sounds

Common alveo-palatal consonants include:

• /tʃ/ as in “chip”: This is a voiceless alveo-palatal affricate. The sound begins with the tongue at the alveolar ridge (similar to /t/) and then moves into a position close to the hard palate (resembling /ʃ/), creating a distinct stop-and-fricative combination.
• /dʒ/ as in “jug”: The voiced counterpart to /tʃ/, /dʒ/ involves a similar articulation pattern but includes vocal cord vibration.
• /r/ as in “rat”: This sound varies among languages; often, it is a voiced alveolar or post-alveolar trill or tap. The tongue is positioned near the alveolar ridge and may lightly touch the palate, creating a rolling or flapping sound.

These examples highlight the dynamic nature of alveo-palatal articulation in human speech.

Velar Sounds

Exploring Velar Articulation

Velar sounds are a distinctive set of consonants produced using the back part of the tongue against the velum or the soft palate, the soft area towards the back of the roof of the mouth. These sounds are integral to numerous languages and contribute significantly to the diversity of human speech.

The production of velar sounds involves a specific positioning of the tongue, which, depending on whether the sound is voiced or voiceless, can create a variety of tones and resonances.

Examples of Velar Sounds

Common velar consonants found in various languages include:

• /k/ as in “cat”: A voiceless velar plosive, where the sound is created by momentarily stopping the airflow with the back of the tongue against the soft palate and then releasing it.
• /g/ as in “go”: The voiced counterpart to /k/, /g/ involves a similar tongue placement but with the addition of vocal cord vibration.
• /ŋ/ as in “sing”: This is a voiced velar nasal, where the back of the tongue closes against the soft palate, and the air resonates in the nasal cavity.

These examples demonstrate the wide use and importance of velar sounds in various languages.

Glottal Sounds

The Nature of Glottal Sounds

Glottal sounds are produced using the glottis, the space between the vocal cords in the larynx. Unlike other consonants that involve the tongue, teeth, or other parts of the mouth, glottal sounds are unique for their reliance on the vocal cords and the glottal space. They add a distinct element to speech, often used for subtle yet important phonetic distinctions.

Examples of Glottal Sounds

Typical glottal sounds include:

• /h/ as in “hat”: This is a voiceless glottal fricative created by the airflow passing through the open glottis, producing a gentle, breathy sound.
• The glottal stop, often represented by a symbol like ʔ, occurs in many languages and dialects. It’s not always represented in writing but is a significant sound in speech. An example is the catch in the throat, often heard in the middle of “uh-oh.”

These sounds, while sometimes less prominent than others, play a crucial role in the phonetic makeup of many languages.

Comparison of Speech Sound Categories

Sound Category	Place of Articulation	Voiced/Voiceless	Examples
Bilabial	Both Lips	Both	/b/ (bat), /p/ (pat), /m/ (mat)
Labiodental	Lower Lip and Upper Teeth	Both	/f/ (fat), /v/ (vat)
Dental	Tongue and Upper Teeth	Both	/θ/ (thin), /ð/ (this)
Alveolar	Tongue and Alveolar Ridge	Both	/t/ (top), /d/ (dog), /s/ (sat), /z/ (zoo), /n/ (nap), /l/ (lap)
Lingua-Palatal	Front of Tongue and Hard Palate	Mostly Voiced	/ʃ/ (shy), /ʒ/ (measure), /j/ (yes)
Alveo-Palatal	Tongue, Alveolar Ridge to Palate	Mostly Voiced	/tʃ/ (chip), /dʒ/ (jug), /r/ (rat)
Velar	Back of Tongue and Soft Palate	Both	/k/ (cat), /g/ (go), /ŋ/ (sing)
Glottal	Glottis (Vocal Cords)	Mostly Voiceless	/h/ (hat), Glottal stop (middle of ‘uh-oh’)
