No The product is a proprietary text-to-speech model with low streaming latency, and building a comparable one requires speech research, large training data, and substantial compute. Wrapping an existing TTS API is easy, but this is not that.
What it would actually take: A competitive version needs a neural TTS model (acoustic model plus vocoder or codec-based architecture), large licensed speech corpora, and GPU training infrastructure. Streaming at about 90 ms requires optimized inference serving and concurrency engineering. This calls for speech-ML researchers and a multi-million-dollar budget.
