A British startup today unveiled new AI humans that blur the line between the virtual and the real. Synthesia calls the digital beings \u201cExpressive Avatars.\u201d They promise the most realistic emotional expressions on the market. <\/span><\/p>\n

Generated by an AI model that\u2019s trained on footage of real actors, the avatars are built for video creation. Users simply enter a text prompt and the synthetic humans read them out on a screen.<\/p>\n

The photorealistic renders are certainly impressive. But what makes them unique is their capacity to convey human feelings.<\/p>\n

Using a technique called \u201cautomatic sentiment prediction,\u201d Synthesia\u2019s AI models infer the emotions within text. This determines the avatar\u2019s tone of voice, body language, and facial expression.<\/p>\n

\u201cThis is definitely the first iteration of avatars that can express emotions and understand the sentiment of the content,\u201d said Victor Riparbe, Synthesia\u2019s CEO and co-founder.<\/span><\/p>\n

The avatars will also always generate entirely new and unique outputs. Feed them the same script twice and they will respond with two different performances<\/span>. In Synthesia\u2019s words, they\u2019ve evolved from \u201cdigital renders\u201d to \u201cdigital actors.\u201d<\/span><\/p>\n

At a product demo on Monday, TNW got to review their acting chops. <\/span><\/p>\n

AI avatars take the stage<\/h2>\n

To this humble critic\u2019s eyes, Synthesia\u2019s avatars are the best GenAI actors to ever perform on the screen.<\/p>\n

The combination of photorealistic faces, emotional gestures, expressive voices, and synchronised movements brings a new level realism to the market.<\/p>\n

Given an upbeat script, the avatars delivered a smile and energetic tone. When fed sadder lines, they offered a sombre inflection and slower speech.<\/p>\n

However, their performances still haven\u2019t escaped the uncanny valley<\/a>. Their main shortcoming is a tendency to slightly exaggerate their emotions. As actors, they\u2019re closer to D-list soap stars than Academy Award winners.<\/p>\n

Another drawback is that their movements are confined to the head, face, and shoulders. As long as that remains the case, they will probably only pose a threat to newsreaders.<\/p>\n

Despite these limitations, the avatars have the potential to unlock new applications.<\/span><\/p>\n
