Broadcom, in partnership with CAMB.AI, has introduced a new on-device artificial intelligence chip designed to handle complex audio tasks like dubbing and audio description — all without an internet connection. The move promises faster translations, stronger privacy protections, and improved accessibility for media consumption.
What the chip does and why it matters
The new Broadcom AI chip performs speech translation, dubbing and descriptive narration directly on the device, rather than relying on remote cloud servers. That on-device processing means audio data stays local, reducing bandwidth use and keeping private content from being uploaded to third-party servers. Broadcom says the technology can support translation into more than 150 languages, although the chip is still in testing and not yet publicly deployed in TVs or consumer gadgets.
Real-world demo and a focus on accessibility
In a demo video shown by the companies, the chip provided audio descriptions and live translations for a clip from the animated film Ratatouille. The visual showed simultaneous written translations on screen while the AI narrated the scene in different languages — a feature that could be particularly useful for viewers with visual impairments or for multilingual households wanting instant localized audio.
Benefits and potential limits
On-device AI brings two clear advantages: faster responses without network latency and improved user privacy since audio never leaves the device. It also reduces ongoing internet consumption because there is no need to stream audio to the cloud for processing. That combination could make smart TVs, streaming boxes and mobile devices much more self-sufficient.
- Privacy: No audio upload to remote servers.
- Latency: Real-time dubbing and translation without an internet connection.
- Bandwidth: Less data used because processing is local.
- Accessibility: Audio descriptions for users with visual impairments.
Questions to watch
Despite the excitement, several unknowns remain. The published demo was short and edited, leaving open questions about how well the chip performs in live, noisy, or complex dialogue scenarios. Accuracy of translations and naturalness of synthesized voices have not been independently verified. Broadcom notes the audio AI model powering this feature is already used by big organizations such as NASCAR, Comcast and the Eurovision Song Contest, which adds credibility, but broader testing will be key.
For now, the Broadcom and CAMB.AI collaboration signals a clear trend: moving more advanced AI functions onto devices to improve speed, privacy and accessibility. When manufacturers integrate the chip into TVs and other consumer electronics, users could get instant, private dubbing and descriptions without relying on an internet connection — if the real-world results match the demo.
