Igbo Speech to Text: How AI is Helping to Preserve and Transcribe the Igbo Language

Igbo is one of the three major languages of Nigeria, spoken by an estimated 45 million people. It is the native language of the Igbo people, who are predominantly found in the southeastern states of Nigeria, as well as in diaspora communities worldwide. The language is known for its musicality, rich vocabulary, and complex tonal system. In recent years, as digital content creation has grown among Igbo speakers, there has been an increasing demand for tools that can convert spoken Igbo into written text accurately.

Why Accurate Igbo Transcription Matters

Transcription of Igbo audio is important for several reasons:

• Preservation of oral culture: Igbo has a strong oral tradition. Transcribing stories, proverbs, and songs helps preserve them for future generations.
• Education: Teachers and students can benefit from written transcripts of Igbo language lessons and lectures.
• Media and content creation: Podcasters, YouTubers, and filmmakers who produce content in Igbo need subtitles to reach a wider audience, including the deaf and hard-of-hearing.
• Research: Linguists and anthropologists studying Igbo dialects and language change require accurate transcriptions of field recordings.

Challenges in Igbo Speech Recognition

Igbo presents several challenges for automatic speech recognition:

• Tonal nature: As mentioned, Igbo uses three tones (high, low, downstep) to distinguish meaning. A speech-to-text system must accurately detect pitch to avoid errors. For example, 'ọ́kwá' (high tone) means 'speech', while 'ọ̀kwá' (low tone) means 'farm'.
• Vowel harmony: Vowels in Igbo must agree in terms of advanced tongue root. This affects inflectional endings and can cause homophones.
• Dialect diversity: The wide range of dialects means that a model trained on one dialect may perform poorly on another. Igbo dialects include:
  • Ọnịcha (often considered the standard)
  • Enuani (spoken in Delta State)
  • Ngwa (southeastern, fast speech)
  • Ika (with Edo influence)
• Nasalization: Nasal vowels are common and must be distinguished from oral vowels. For instance, 'ọ́nụ́' (with nasalization) means 'mouth', while 'ọ́nụ́' without nasalization is not a word.

Speechyou overcomes these challenges by using a deep learning model trained on a diverse Igbo corpus, with dialect-specific options and tone mark output.
