# Language Identification Modes

Language identification can run in three modes:

- CUMULATIVE. Cumulative language detection returns the running identification score at periodic intervals. This score is the score for all the audio from the start to the current point. This mode is the most reliable way to determine the language for a whole file (assuming it contains only one language), because the final result is calculated across the entire file.
- SEGMENTED. Segmented language detection splits the incoming audio into fixed-sized chunks and returns the identification results for each chunk, independent of the results of neighboring chunks. You can use this mode to determine if there are multiple languages present, although it does not give the exact boundary points.
- BOUNDARY. Boundary detection-based language recognition seeks to determine boundaries in the audio where the language changes, and returns the identification results between boundaries. Although this mode is potentially powerful, it can be more difficult to configure than the other two modes.
