Background of the study
Advancements in voice recognition technology have revolutionized communication by converting speech to text, yet challenges remain when these systems are applied to diverse linguistic varieties. Nigerian English, characterized by its unique phonetic and syntactic features, presents specific challenges for accurate voice recognition (Adebayo, 2023). Standard voice recognition systems are typically optimized for conventional English accents and may not account for the distinct pronunciation, intonation, and colloquial expressions found in Nigerian English. These limitations can result in lower accuracy and hinder the technology’s effectiveness in critical sectors such as education, healthcare, and business. Recent developments in machine learning and artificial intelligence offer promising avenues to improve these systems, but significant adaptation is required to handle linguistic diversity (Chinwe, 2024). This study investigates the performance of current voice recognition technology in processing Nigerian English, aiming to identify linguistic challenges and propose enhancements that accommodate local language nuances (Ike, 2023).

Statement of the problem
Despite advancements, existing voice recognition systems often fail to accurately process Nigerian English due to its distinct linguistic characteristics. This shortfall impedes user experience and restricts the technology’s application in sectors where accurate transcription is critical (Okoro, 2024). The inability to recognize regional accents, idiomatic expressions, and contextual variations reduces system reliability and usability. This study aims to identify these limitations and explore technological adaptations that can improve the performance of voice recognition systems for Nigerian English speakers, thereby increasing inclusivity and effectiveness.

Objectives of the study:

  1. To assess the accuracy of current voice recognition systems for Nigerian English.
  2. To identify linguistic challenges affecting voice recognition performance.
  3. To recommend technological adaptations for enhanced inclusivity.

Research questions:

  1. How accurately do current systems process Nigerian English?
  2. What linguistic factors contribute to reduced recognition accuracy?
  3. How can technology be adapted to better handle Nigerian English nuances?

Research hypotheses:

  1. Current systems exhibit lower accuracy for Nigerian English compared to standard English.
  2. Phonetic variations in Nigerian English adversely affect system performance.
  3. Tailored adaptations can significantly improve recognition accuracy.

Significance of the study (100 words):
This study is significant as it addresses the gap in voice recognition technology for Nigerian English speakers. The findings will guide developers and policymakers in creating more inclusive systems that accommodate linguistic diversity, ultimately enhancing digital accessibility and communication efficiency (Akinyemi, 2023).

Scope and limitations of the study:
This study is limited to assessing voice recognition technology for Nigerian English speakers, focusing on linguistic and technological challenges.

Definitions of terms:

  1. Voice Recognition Technology: Systems that convert spoken language into text.
  2. Nigerian English: The variety of English spoken in Nigeria, characterized by unique linguistic features.
  3. Accuracy: The degree to which voice recognition systems correctly interpret spoken input.
