No. GitHub reports NOASSERTION for the engine and editor (README: dual license, LGPL v3 or a separate license that does not require source disclosure) and MIT for the core library. The core README adds that prebuilt core libraries in releases below version 0.16 are under another license. The voice models (VVM) are licensed separately and their terms are in a README inside the download. Rationale: READMEs, LICENSE file and the core user guide were read. Counterevidence: none found Uncertainty: The contents of the separate (no-source-disclosure) license were not read; the core release assets were not inspected.
