Course content

8 Chapters • 40 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Foundations of Speech Production

  • Lesson 1 • Introduction to the IPA

    Introduces the International Phonetic Alphabet as a precise notation system for all sounds. Provides the transcription tools needed for every subsequent chapter.

  • Lesson 2 • Anatomy of the Vocal Tract

    Maps the lips, teeth, tongue, palate, pharynx, and larynx as active speech organs. Establishes anatomical vocabulary used throughout the course.

  • Lesson 3 • Resonance and Tone Placement

    Identifies chest, oral, and nasal resonating chambers and their effect on timbre. Teaches students to consciously shift resonance for clarity.

  • Lesson 4 • Breath Support and Airflow

    Explains diaphragmatic breathing as the power source for speech. Connects controlled airflow to consistent volume and tone quality.

  • Lesson 5 • Phonation and Vocal Fold Action

    Describes how vocal folds vibrate to produce voiced sound. Links healthy phonation habits to long-term vocal durability.

Chapter 2See details

Voice Quality and Vocal Health

  • Lesson 1 • Pitch Range and Flexibility

    Expands the usable pitch range through gliding and sirening exercises. A wider pitch range supports expressive intonation and reduces monotone delivery.

  • Lesson 2 • Posture and Alignment for Voice

    Links spinal alignment and head position to unrestricted airflow and resonance. Correct posture is the structural prerequisite for all voice quality work.

  • Lesson 3 • Vocal Hygiene Practices

    Establishes evidence-based habits that protect vocal fold health over a career. Covers hydration, rest, environmental factors, and warning signs of vocal fatigue.

  • Lesson 4 • Vocal Warm-Down and Recovery

    Introduces cool-down routines that reduce post-performance vocal strain. Consistent warm-down extends vocal longevity for high-demand professional speakers.

  • Lesson 5 • Volume Control and Projection

    Trains breath-supported projection without strain, replacing throat-pushing habits. Students calibrate volume to room size and microphone conditions.

Chapter 3See details

Vowel Production and Clarity

  • Lesson 1 • Vowel Length and Stress

    Examines how duration and stress interact to signal meaning in English. Connects vowel length control to natural-sounding rhythm.

  • Lesson 2 • Diphthongs and Triphthongs

    Trains smooth gliding movement between vowel targets within a single syllable. Addresses incomplete glides that blur word boundaries.

  • Lesson 3 • Short and Long Monophthongs

    Drills the pure single-target vowels of American English in isolation and in words. Targets common substitution errors that reduce intelligibility.

  • Lesson 4 • The Vowel Quadrilateral

    Explains the tongue-position grid that maps all vowel sounds. Students use the quadrilateral to diagnose and correct vowel placement errors.

  • Lesson 5 • Vowel Clarity in Connected Speech

    Applies isolated vowel skills to continuous sentences and paragraphs. Identifies coarticulation effects that alter vowel targets in context.

Chapter 4See details

Consonant Precision and Placement

  • Lesson 1 • Fricatives and Affricates

    Trains precise constriction for turbulent airflow sounds and their affricate combinations. Targets the most common professional intelligibility errors.

  • Lesson 2 • Consonant Classification System

    Organises consonants by place of articulation, manner of production, and voicing. Provides a diagnostic framework used in all subsequent consonant work.

  • Lesson 3 • Stops and Nasals

    Drills complete closure and release for bilabial, alveolar, and velar stops. Adds nasal resonance control for /m/, /n/, and /ŋ/.

  • Lesson 4 • Consonant Clusters and Final Sounds

    Practises multi-consonant sequences at word boundaries and in final position. Eliminates cluster reduction and final-consonant deletion.

  • Lesson 5 • Approximants and Liquids

    Develops smooth, non-turbulent articulation for glides and liquids. Addresses /r/ and /l/ confusion and /w/ and /j/ weakening.

Chapter 5See details

Stress, Rhythm, and Intonation

  • Lesson 1 • Intonation Patterns

    Maps falling, rising, and fall-rise tones to their communicative functions. Students use intonation to signal statements, questions, and uncertainty.

  • Lesson 2 • Sentence Stress and Focus

    Teaches content-word versus function-word stress to highlight key information. Students manipulate focus stress to change implied meaning.

  • Lesson 3 • Word Stress Patterns

    Identifies primary and secondary stress placement rules across word classes. Correct stress prevents miscommunication in professional vocabulary.

  • Lesson 4 • Rhythm and Timing

    Develops the stress-timed beat of English through metronome and clapping drills. Consistent rhythm signals fluency and confidence to listeners.

  • Lesson 5 • Prosody in Extended Discourse

    Applies all prosodic features to paragraphs, presentations, and dialogue. Integrates stress, rhythm, and intonation into a unified delivery style.

Chapter 6See details

Articulation Agility and Speed

  • Lesson 1 • Minimal Pair Contrast Drills

    Trains fine motor discrimination between near-identical sounds through rapid alternation. Minimal pair accuracy is the benchmark for professional-level precision.

  • Lesson 2 • Tongue Twisters as Diagnostic Tools

    Uses targeted tongue twisters to expose specific articulation weaknesses. Each twister isolates a phoneme pair or cluster for focused remediation.

  • Lesson 3 • Agility in Real-Text Passages

    Transfers drill-level agility to authentic professional texts such as scripts and reports. Measures words-per-minute alongside intelligibility scores.

  • Lesson 4 • Speed Progression Techniques

    Applies chunking, shadowing, and tempo-ramping to increase delivery rate without loss of clarity. Students set personal speed benchmarks and track improvement.

  • Lesson 5 • Articulatory Warm-Up Routines

    Establishes a systematic pre-speech warm-up targeting lips, tongue, and jaw. Consistent warm-ups reduce errors and prevent fatigue during extended speaking.

Chapter 7See details

Accent Awareness and Neutralisation

  • Lesson 1 • Common Regional Vowel Shifts

    Examines widespread American regional vowel patterns and their intelligibility consequences. Students practise moving vowels toward a broadly intelligible target.

  • Lesson 2 • Identifying Personal Accent Features

    Guides students through self-recording and phonetic analysis to map their own accent profile. Creates an individualised target list for focused practice.

  • Lesson 3 • Prosodic Accent Features

    Targets syllable-timed rhythm, tonal patterns, and stress placement imported from other languages. Prosodic adjustment often yields the greatest intelligibility gain.

  • Lesson 4 • Understanding Accent and Dialect

    Distinguishes accent from dialect and clarifies the professional goal of intelligibility over elimination. Frames accent work as expansion, not correction.

  • Lesson 5 • Non-Native Consonant Patterns

    Addresses the most frequent consonant substitutions from major language backgrounds. Provides targeted drills for each identified pattern.

Chapter 8See details

Applied Diction in Professional Contexts

  • Lesson 1 • Reading Aloud and Oral Interpretation
