Frequently Asked Questions
AivisSpeech vs StoryFile: which should you choose?
Choose StoryFile if you need authentic, filmed conversational AI for historical or legacy preservation with institutional credibility; choose AivisSpeech if you need flexible, high-quality generative TTS for content creation or dialogue systems, especially in Japanese, with strong local and cloud options.
Can StoryFile generate responses not recorded in the interview?
No, StoryFile only responds with pre-recorded footage indexed by AI. For entirely synthetic responses, consider StoryFile's Lookalike generative avatar or AivisSpeech.
Does AivisSpeech support languages other than Japanese?
Currently, AivisSpeech is centered on Japanese. The models and voice data are primarily Japanese, though the engine might process other languages with limited quality.
What hardware does StoryFile require?
StoryFile can be deployed as a digital twin accessible via web or within kiosks. They also offer HOLOGLASS, a 3D holographic display for lifelike physical presence.
Is AivisSpeech free for commercial use?
Yes, many models use ACML/ACML-NC/CC0 licenses that allow commercial use without credit. Always check each model's license on AivisHub.
Can I create my own voice model with AivisSpeech?
Yes, using AivisBuilder (in development) or AIVM Generator, you can create custom voice models from your recordings and share them via AivisHub.
How does StoryFile's digital twin for public figures work?
Subjects record hundreds of conversational responses. AI indexes them and maps query intents to the best video answer, enabling natural dialogue. Example: Kara Swisher's CNN digital twin.
Does AivisSpeech require internet?
The desktop app works fully offline. For the cloud API features, internet is needed. Local synthesis uses only CPU and no GPU required.
Which tool is better for real-time interactive exhibits?
StoryFile is purpose-built for interactive exhibits with real video responses and hardware like HOLOGLASS. AivisSpeech can power voice interfaces but lacks video output.
