AUDIO AS A BASIC MEDIA FOR CALL MATERIAL

(The Role, Principles, and Application of Audio in Computer-Assisted Language Learning)

1. Introduction

Audio is one of the earliest and most fundamental media used in Computer-Assisted Language Learning (CALL). Before sophisticated multimedia tools were developed, CALL systems relied heavily on audio-based drills, listening comprehension tasks, and pronunciation training.

Today, audio remains a core component of CALL because language itself is inherently auditory. Learners must hear authentic language input to build comprehension, improve pronunciation, internalize rhythm, and understand real communication patterns.

2. Why Audio Is Essential in CALL

Audio plays a central role in digital language learning for several reasons:

1. Language is an auditory system

Learners must hear words in context to understand meaning, stress, intonation, and pronunciation.

2. Exposure to authentic input

Audio can deliver real voices, dialects, speech speeds, and real-life communication.

3. Supports independent learning

Students can repeat audio as many times as needed without teacher intervention.

4. Suitable for all proficiency levels

From beginner vocabulary pronunciation to advanced lecture listening.

5. Enhances multimodal learning

Audio combined with text, images, or video builds stronger comprehension.

Thus, audio is not just supplementary; it is foundational in CALL material design.

3. Types of Audio Used in CALL

CALL materials commonly include the following categories of audio:

A. Instructional Audio

Used to give directions or guide learners through a task.

Example: “Listen to the dialogue and answer the questions.”

B. Dialogues and Conversations

Authentic or scripted spoken interactions used for:

listening comprehension
speaking modeling
conversational routines

C. Pronunciation Models

Audio clips that focus on:

phonemes
word stress
intonation patterns
rhythm of speech

Can be paired with waveform visualizations or repeat-after-me tasks.

D. Vocabulary Pronunciations

Individual words or short phrases read clearly to teach:

pronunciation
stress patterns
correct syllabification

E. Monologues

Short speeches, announcements, presentations, or stories used for:

note-taking activities
comprehension tasks

F. Authentic Environmental Sounds

Used for contextual learning:

airport announcements
street sounds
classroom interactions

These create realistic learning contexts.

📘 4. Principles for Using Audio in CALL Material

The effectiveness of audio in CALL depends on how it is designed and integrated.

1. Clarity and Quality

Audio must be clear, noise-free, and well-paced.

2. Authenticity

Whenever possible, use real speakers rather than robotic or artificial voices.

3. Graded Difficulty

Start with slow, controlled recordings → gradually increase speed and complexity.

4. Repetition and Replay Options

Learners should be able to replay audio as needed.

5. Integration with Tasks

Audio should not stand alone; it must be paired with activities such as:

comprehension questions
note-taking
transcription
pronunciation practice

6. Cultural Relevance

Use audio that reflects real communication practices of the target language.

📘 5. CALL Activities Using Audio

Below are the most common audio-based CALL activities:

A. Listening Comprehension Tasks

Learners listen to a passage and answer:

multiple choice
true/false
short answer
matching

B. Pronunciation Practice

Learners imitate the audio model to practice:

segmental sounds (vowels/consonants)
suprasegmental features (stress, rhythm, intonation)

Technologies like speech recognition (e.g., Google, AI tools) support pronunciation assessment.

C. Dictation & Partial Dictation (Cloze Listening)

Students listen and fill in missing words.

D. Sound Discrimination Activities

Learners identify minimal pairs:

ship / sheep
bit / beat
cap / cup

E. Listening for Detail & Listening for Gist

Activities designed for:

main idea
specific information
inference

F. Dialogue Completion

Students listen to a conversation and complete missing parts.

G. Shadowing Activities

Learners repeat speech simultaneously to improve fluency.

📘 6. Audio Integration in Digital Platforms (Including PowerPoint)

Although audio is commonly used in specialized CALL software, it is also easy to integrate in simple tools such as PowerPoint, mobile apps, and websites.

Using Audio in PowerPoint (CALL Application)

PowerPoint allows you to embed:

MP3 files
WAV recordings
Dialogue tracks
Sound effects
Pronunciation clips

Features for CALL Audio Integration in PowerPoint

Click-to-play buttons
Auto-play audio
Audio tied to quiz questions
Listening comprehension slides
Glossary words with pronunciation icons

Examples of CALL Audio Activities in PowerPoint

Listening to a conversation and choosing the correct answer
Clicking vocabulary words to hear pronunciation
Playing sample sentences to model grammar usage

📘 7. Advantages of Using Audio for CALL Material

1. Supports auditory learning

Many learners benefit significantly from hearing language input.

2. Increases authenticity

Real accents, speech speed, and language usage can be included.

3. Enhances comprehension

Audio contextualizes meaning more effectively than text alone.

4. Easy to integrate with other media

Audio + image → vocabulary

Audio + text → listening

Audio + video → multimodal learning

5. Encourages independent practice

Students can replay, review, and listen anytime.

📘 8. Limitations and Considerations

While audio is powerful, some challenges exist:

1. Overdependence

Learners may rely solely on listening without reading or speaking practice.

2. Technical issues

Low-quality audio or poor speakers may hinder comprehension.

3. Need for scaffolding

Beginners require supports such as:

transcripts
vocabulary lists
guided questions

4. Cultural variety

Accents differ widely; exposure must be balanced.

9. Conclusion

Audio remains a basic yet essential medium in Computer-Assisted Language Learning. It provides authentic input, enhances comprehension, supports pronunciation, and improves listening skills. Modern CALL environments—including simple platforms like PowerPoint—can fully integrate audio to create effective and engaging language learning experiences.

In CALL material design, audio is not merely an add-on; it is a primary foundation for building communicative competence and real-world language proficiency.
