In-House Studio Level Voice Cloning Software

I am seeking a highly accurate and natural sounding studio level voice cloning software that can be hosted in-house. The software should be capable of utilizing 3-4 hours of available voice material. Key Features: - High accuracy and natural sound: The primary requirement of the software is to produce voice outputs that are indistinguishable from the original voice. - Multiple accents and dialects: The software should have the capacity to generate voices with a variety of accents and dialects. - Different emotional tones: It should also be able to modulate the voice to convey different emotional tones. - Variable speaking speeds: The ability to change the pace of speech is also essential. The software will be used primarily for commercial recordings, so a user-friendly interface is a plus but not a necessity. Ideal candidates for this project should have experience with voice cloning technology, preferably with developing or implementing in-house solutions.
