Transform text into studio-quality voiceovers with enterprise-grade AI synthesis.
Professional-grade neural text-to-speech converting text into lifelike speech for global applications.
Ivona, originally a pioneer in high-fidelity speech synthesis, was acquired by Amazon in 2013 and has since been fully integrated into the Amazon Polly ecosystem. In 2026, the Ivona engine serves as the backbone for Amazon Polly’s legacy and high-fidelity neural voices. The technical architecture utilizes advanced Deep Learning and Generative AI models to deliver human-like intonation, cadence, and emotion. Unlike standard TTS, the current iteration provides 'Neural TTS' (NTTS) which employs a sequence-to-sequence model to generate speech that is indistinguishable from human recordings. The platform is strategically positioned for enterprise-scale deployment, offering massive concurrency, sub-millisecond latency, and support for dozens of languages and varied accents. For developers, it provides a robust API-driven workflow capable of generating dynamic audio for IVR systems, e-learning platforms, and assistive technologies. The integration with AWS allows for seamless data flow between S3, Lambda, and Polly, making it the industry standard for scalable audio content generation.
