The "top" demo of today is just the beginning. Acapela is integrating —where the TTS analyzes the sentiment of your text and automatically adjusts without manual tags. In the latest beta versions of the demo (available upon request), you can see the engine switch from a happy tone to a sympathetic tone based on words like "unfortunately" or "amazing."
Acapela’s neural engines must distinguish between past tense "read" (red) and present tense "read" (reed), the metal "lead" (led) vs. the verb "lead" (leed), and the noun "wind" vs. the verb "wind." A top demo handles this flawlessly. acapela tts demo top
