Dubbing and Its Impact on Speech Perception and Language Acquisition

Introduction

The issue of dubbing in film and television has long been debated in the context of language learning, cultural transmission, and cognitive processing. While dubbing makes audiovisual content more accessible to native audiences, it may also disrupt the natural connection between speech, gesture, and articulation, thereby affecting how language is processed and acquired. I am aware of both advantages and disadvantages, particularly in relation to speech perception theories, including those of Gibson (1966, 1979), Fowler (1986), and Liberman & Mattingly (1985). Furthermore, the concept of “mimism” as proposed by Marcel Jousse (1925) offers valuable insight into the role of multimodal input in language acquisition. This article aims to present a fair and balanced discussion of dubbing, its implications for language learners, and the potential ways to mitigate its drawbacks in an EFL setting.

Theoretical Foundations: Perception and Articulation

Understanding dubbing’s influence on speech perception requires engaging with fundamental theories of perception and speech production.

• Gibson’s Direct Perception (1966, 1979): Gibson posited that perception is direct and unmediated — we extract information from our environment based on affordances rather than through inferential processing. In the context of dubbing, however, there is a disruption in the audiovisual congruence: the affordances of visual articulatory gestures do not match the linguistic input. This discrepancy might confuse learners who rely on embodied cues to process speech.
• Fowler’s Event Perception (1986): Fowler extended Gibson’s ideas to speech perception, suggesting that listeners extract articulatory gestures rather than merely interpreting acoustic signals. When watching a dubbed film, a learner is faced with conflicting information — gestures from one language and speech sounds from another. This mismatch may hinder the natural acquisition of phonetic and prosodic features of the target language.
• Liberman & Mattingly’s Motor Theory of Speech Perception (1985): This theory suggests that speech perception and production are intricately linked — humans perceive speech in terms of how they would produce it. Dubbing removes the natural visual cues associated with articulation, making it more difficult for learners to connect sounds with their motor counterparts.
• Marcel Jousse’s Theory of Mimism (1925): Jousse emphasized that language is inherently gestural and mimetic, with oral tradition relying heavily on the interplay of movement, rhythm, and speech. Dubbing, by severing the link between original gestures and speech, may interfere with the learner’s ability to develop an embodied understanding of the language.

Advantages of Dubbing for EFL Learners

Despite its potential drawbacks, dubbing also offers certain benefits that must be acknowledged:

1. Comprehensibility and Engagement: Dubbing allows learners to access content in a more familiar linguistic form, enabling better comprehension of complex narratives. This increased engagement can foster cultural literacy and broaden learners’ exposure to diverse storytelling traditions.
2. Vocabulary Acquisition: While dubbed content might not provide authentic phonetic input, it still offers valuable lexical exposure. Learners can acquire new vocabulary and idiomatic expressions in their native language, which they may later encounter in the target language.
3. Reduction of Cognitive Load: For beginner learners, dubbed films allow them to focus on visual and narrative aspects without struggling to process unfamiliar phonetic information. This can be particularly helpful in scaffolding learning for lower proficiency levels.
4. Access to Multilingual Content: In multilingual contexts, dubbing enables learners to explore content across multiple languages without being restricted by their current level of proficiency in any one language.

Disadvantages of Dubbing for Language Learning

However, the disadvantages of dubbing for EFL learners are significant and warrant careful consideration:

1. Disruption of Speech Perception and Production: Given that speech perception and production are closely linked (Liberman & Mattingly, 1985), exposure to dubbed content may interfere with learners’ ability to develop accurate pronunciation, rhythm, and intonation in the target language.
2. Mismatch Between Visual and Auditory Input: The incongruence between articulatory gestures and dubbed speech (Fowler, 1986) can lead to misinterpretation of phonemes, particularly for languages with distinct prosodic patterns.
3. Reduced Exposure to Natural Speech Patterns: Authentic speech includes hesitations, contractions, and variations in prosody. Dubbed speech, by contrast, is often artificial and rigidly synchronized to lip movements, reducing learners’ exposure to natural speech variation.
4. Potential for Fossilization of Accents: Learners who rely primarily on dubbed content may fail to develop sensitivity to authentic pronunciation, reinforcing strong L1-influenced accents.

Implications for EFL Teaching and Recommendations

Given these advantages and disadvantages, how should EFL educators address the issue of dubbing? Rather than advocating for or against it outright, a balanced approach can be adopted:

• Use Dubbing as a Transitional Tool: Beginner learners may benefit from dubbed content as a means of engaging with foreign-language media before progressing to subtitled or original-language content.
• Pair Dubbing with Authentic Listening Activities: Teachers can supplement dubbed media with authentic recordings, such as podcasts, audiobooks, and interviews, to provide exposure to natural speech patterns.
• Highlight Phonetic Differences: EFL learners should be made aware of discrepancies between dubbed pronunciation and native articulation. Activities such as shadowing, phonetic drills, and minimal pair exercises can help reinforce accurate pronunciation.
• Incorporate Visual and Kinetic Learning: Jousse’s emphasis on mimism suggests that speech and gesture should be taught together. Teachers can use drama, role-play, and physical gestures to reinforce the embodied nature of speech.
• Encourage Critical Viewing: Learners should be encouraged to analyze dubbed films critically, comparing the original speech with dubbed versions to understand phonetic, prosodic, and semantic differences.

Conclusion

Dubbing presents both advantages and disadvantages in the context of language learning. While it provides an accessible gateway to foreign-language content, it also disrupts the natural relationship between articulation, gesture, and perception. The theories of Gibson, Fowler, Liberman & Mattingly, and Jousse all highlight the importance of embodied and direct perception in speech processing, suggesting that an overreliance on dubbed media may hinder phonetic and prosodic development. However, with strategic pedagogical interventions, educators can mitigate these drawbacks, ensuring that learners benefit from diverse linguistic input while developing accurate and natural speech production. The key lies in fostering a balanced, multimodal approach that respects the complexity of speech perception and production while making foreign-language media accessible and engaging for learners.
