Abstract
Recent years have witnessed notable advancements in the areas of speech, speaker and language/dialect recognition. However, many of the emerging scientific principles appear to be drifting to the sidelines with the assumption that access to larger amounts of data is all that is required to address a growing range of issues relating to new scenarios. This study surveys several challenging domains in formulating effective solutions in realistic speech data, and in particular the notion of using naturalistic data to better reflect the potential effectiveness of new algorithms. Our main focus is on intra-speaker mismatch and speech variability issues due to (i) differences in noisy speech with and without Lombard effect and a communication factor, (ii) realistic field data in noisy and increased cognitive load conditions, (iii) speech variability introduced by whispered speech, and (iv) dialect identification using found data. Finally, we study speaker-environment and speaker-speaker interactions in a newly established, fully naturalistic Prof-Life-Log corpus. The specific outcomes from this study include an analysis of the strengths and weaknesses of simulated vs. actual speech data collection for research.
