Nigerian Pidgin English

Nigerian Pidgin English, often simply called "Pidgin" or "Naija", is one of the most widely spoken languages in West Africa. Estimates suggest that over 75 million Nigerians use it regularly, either as a first language or as a lingua franca for communication across the country's more than 500 ethnic groups. Despite its massive speaker base, Pidgin has historically been overlooked by language technology.

What makes Pidgin distinctive

Nigerian Pidgin is an English-lexified creole, meaning most of its vocabulary derives from English but its grammar, phonology, and idiomatic expressions are distinctly its own. "I dey go market" (I am going to the market) and "wetin dey happen?" (what is happening?) illustrate how Pidgin restructures English words into its own syntactic patterns. The language also borrows heavily from Yoruba, Igbo, Hausa, and other Nigerian languages, making it a fascinating linguistic melting pot.

Because of its oral tradition and informal status, there is no single standardised spelling system. The same word might be written differently by different speakers, which creates unique challenges for ASR systems that rely on consistent text representations during training.

Challenges for transcription

Building accurate speech recognition for Pidgin requires purpose-collected training data, since standard English models consistently misinterpret Pidgin speech. The tonal patterns, vowel systems, and code-mixing with indigenous languages all differ from any variety of standard English. Additionally, Pidgin varies regionally, the Pidgin spoken in Lagos sounds different from what you hear in Port Harcourt or Benin City.
