Following the acquisition, IVONA's direct development as a standalone brand ceased, with Amazon funneling focus toward cloud-based solutions like Amazon Polly .
The commercial text‑to‑speech (TTS) platform (now part of Amazon Polly) provides a range of high‑quality synthetic voices, among which the male English voice “Eric” is frequently used in e‑learning, accessibility, and interactive systems. This paper presents a systematic evaluation of Eric’s acoustic naturalness, intelligibility, and expressive capability. We combine objective metrics (Mel‑Cepstral Distortion, Word Error Rate) with subjective listening tests (Mean Opinion Score, ABX discrimination) across three use‑cases: narration, dialog, and assistive reading. Results show that Eric attains an average MOS of 4.3 ± 0.2 on a 5‑point scale, comparable to state‑of‑the‑art neural TTS systems, while maintaining low computational overhead. The paper also discusses licensing constraints, integration workflows, and recommendations for developers seeking to employ Eric in production environments. text to speech eric ivona
In January 2013, Amazon acquired Ivona Software. The Ivona technology became the underlying engine for (Amazon's cloud TTS service) and the voice assistant Alexa . Consequently, the "Eric" voice is now part of Amazon's broader speech infrastructure, though it retains a legacy following among users of desktop TTS software. Following the acquisition, IVONA's direct development as a
