New TTS model simulates human Lombard effect for clearer speech

Researchers have developed a new text-to-speech (TTS) model that can simulate the Lombard effect, a phenomenon where humans speak louder and clearer in noisy environments. The model utilizes flow-matching and pseudo-labels for vocal effort and articulation to achieve continuous control over these speech characteristics. This allows for word-level emphasis and has been shown to improve clarity and intelligibility in simulated noisy conditions. AI

IMPACT This research could lead to more natural and understandable synthesized speech in noisy environments.

    Synthesizing the Lombard Effect: Multi-Level Control of Speech Clarity and Vocal Effort in TTS

    Humans tend to speak louder and clearer in challenging environments, such as noisy conditions or when addressing hearingimpaired listeners, which is called Lombard effect. To simulate this behavior in speech synthesis systems, we introduce a flow-matching based text-to-speech (TT…
