Parallel English–Akan Navigation Dataset Parallel English–Akan Navigation Dataset

This corpus was developed to support assistive navigation technology for visually impaired Akan-speaking users, including a smart GPS navigation aid that delivers spoken guidance in Akan. It contains a curated bilingual parallel corpus developed to support domain-specific speech and language technologies, primarily, automatic speech recognition (ASR) and text-to-speech (TTS). The corpus was constructed to address the scarcity of navigation and accessibility-specific data for low-resource African languages, particularly Akan, and to support voice-enabled mobility aids for visually impaired users. It comprises 6,600 English–Akan parallel sentences spanning seven functional navigation categories: route instructions, hazard and safety alerts, contextual orientation cues, status and confirmation feedback, landmark and location references, environmental descriptions, and system status prompts. Navigation topics represented include turn-by-turn route guidance, gutter and vehicle hazards, road crossing, cardinal direction and spatial positioning, terrain and elevation cues, on-track and off-track confirmations, campus halls and academic buildings, gates and junctions, indoor and outdoor environmental description, and device status and connectivity prompts. The corpus also contains approximately 9.03 hours of Akan audio recordings (one male (IM), one female voice (HA)) corresponding to the 6,600 sentences.
