Analysis of the Fastest Spoken Languages

Introduction

• Curiosity arises from watching a telenovela about the fastest spoken language.
• Reference to a 2019 study analyzing the speed and information rate of languages.

Study Overview

• Differences in speaking rates exist individually and regionally within the same language.
• Study involved 17 languages covering over 3 billion people and 9 language families, including unique ones like Basque.
• Native speakers read translations of the same message, measuring speed and syllables spoken.

Key Findings

Fastest Spoken Languages

• Japanese is the fastest, followed by Spanish, which averages 8 syllables per second; English averages 6 syllables per second.
• Notably, speed wasn't the primary focus; rather, information rate was the ultimate goal.

Information Rate and Density

• Information density is assessed by how much information each syllable conveys.
• The study utilized Shannon entropy, a concept developed by Claude Shannon, to calculate information density and rate.

Spanish vs. English

• Spanish uses more syllables but is quicker, resulting in equal information conveyance over time as English.
• Both exhibit an average information rate of about 43 bits per second.

Universal Patterns

• Faster spoken languages typically carry less information per syllable.
• Across all studied languages, the information rate averages approximately 39 bits per second.

Study Caveats and Limitations

• Translations may not be identical in the information conveyed across languages.
• Languages incorporate unique elements (e.g., French gender in professions, Japanese honorifics).

Conclusions

• Most languages convey information at similar rates, suggesting a limit on how quickly the brain processes spoken information.
• Potentially, the average rate across activities (speaking, reading, etc.) indicates a neurological processing constraint.
• Ongoing research aims to explore these findings across more languages and corroborate initial results.

Additional Insights

• The study hinted that brain limitations in processing might affect communication efficacy.
• The hypothesis supported by extending studies in the journal Neuron correlating them with other cognitive activities, suggesting a natural limit in processing speed.

Acknowledgment

• Video supported by Brilliant, a learning platform offering interactive lessons.

Future Directions

• Further investigation needed, given the exclusion of major languages in the initial study and varying results from subsequent research.
