That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 58 of the 72 other AI voice generators grade higher. It costs $4,000 a year. - You could not: A voice model, which you can rent by the minute but not make. - You could not: An AI agent, with the models and the safeguards behind it. - You could not: Speech turned into text you can trust. - You could not: An API that other software can build on. - You could not: What a company asks for before it lets staff use something: SOC 2.
