Voxtral TTS is a new multilingual text-to-speech AI model that can generate natural speech from just 3 seconds of reference audio. In human evaluations, it achieved a 68.4% win rate over ElevenLabs Flash v2.5 for voice cloning, demonstrating superior naturalness and expressivity.
Researchers introduce SyncSpeech, a new text-to-speech model that combines autoregressive and non-autoregressive approaches using a Temporal Mask Transformer architecture. The model achieves 5.8x lower first-packet latency and 8.8x improved real-time performance while maintaining comparable speech quality to existing models.
Researchers have developed PV-VASM, a probabilistic framework for verifying the robustness of voice anti-spoofing models against deepfake attacks. The model-agnostic approach estimates misclassification probability under various speech synthesis techniques including text-to-speech and voice cloning, providing formal robustness guarantees against unseen generation methods.
Researchers propose HIR-SDD, a new framework combining Large Audio Language Models with human-inspired reasoning to detect speech deepfakes. The method aims to improve generalization across different audio domains and provide interpretable explanations for deepfake detection decisions.
Research demonstrates that LoRA fine-tuning of large language models significantly improves text-to-speech systems, achieving up to 0.42 DNS-MOS gains and 34% SNR improvements when training data has sufficient acoustic diversity. The study establishes LoRA as an effective mechanism for speaker adaptation in compact LLM-based TTS systems, outperforming frozen base models across perceptual quality, speaker fidelity, and signal quality metrics.
Researchers introduce AG-REPA, a new method for improving audio generation models by strategically selecting which neural network layers to align with teacher models. The approach identifies that layers storing the most information aren't necessarily the most important for generation, leading to better performance in speech and audio synthesis.
Developers can now access next-generation audio models through an API that includes advanced text-to-speech capabilities. The new models allow for instructional voice customization, enabling developers to specify speaking styles like 'sympathetic customer service agent' for enhanced voice agent applications.
OpenAI provides technical insights into Voice Engine, their text-to-speech model technology, along with details about their safety research approach. The article explores the underlying technology and safety considerations for their voice synthesis capabilities.
Researchers developed a two-stage prompt selection strategy for zero-shot text-to-speech synthesis that improves emotional intensity and speaker consistency. The method evaluates prompts using prosodic features, audio quality, and text-emotion coherence in a static stage, then uses textual similarity for dynamic prompt selection during synthesis.
Researchers introduce NV-Bench, the first standardized benchmark for evaluating nonverbal vocalizations in text-to-speech systems. The benchmark includes 1,651 multilingual utterances across 14 categories and proposes new evaluation metrics that show strong correlation with human perception.
Descript leverages OpenAI models to enable scalable multilingual video dubbing by optimizing translations for both semantic accuracy and timing synchronization. This technology allows dubbed speech to sound natural across different languages while maintaining proper video-audio alignment.
Researchers propose ZeSTA, a domain-conditioned training framework that improves personalized speech synthesis by better integrating synthetic and real speech data. The method addresses speaker similarity degradation issues when using zero-shot text-to-speech augmentation with limited real recordings.
