OpenAI and Microsoft continue the battle with Google in artificial intelligence by implementing Vall-E, the new voice chatbot. This is a speech synthesis software that can simulate the human voice after just three seconds of listening.

In other words, this is the latest piece of the generative artificial intelligence system developed by Microsoft and OpenAI, with which since 2019 the colossus of Bill Gates is linked by a multi-year, multibillion-dollar partnership.

Vall-E: all the details about the new chatbot from OpenAI and Microsoft

Valle-E is a tool of AGIArtificial General Intelligence, that is, a “general” or “strong” artificial intelligence that can simulate human intelligence. Thus, as opposed to what we have known so far, which is “narrow” or “weak” AI.

The latter is able to respond with preset actions to specific tasks, but not to react to an unplanned action. In recent years, AI chatbots have not performed as well as its creators expected because they were limited to small tasks and had a high error rate.

Valle-E was developed to be used with high-quality speech synthesis tools and to create original audio from an example sample. OpenAI defines Valle-E as a “natural codec language model,” as its operation is based on a technology called EnCodec.

The startup, funded by Elon Musk and Sam Altman, among others, also boasts the creation of ChatGPT, a chatbot that can sustain an interactive conversation with users by remembering and learning from previous actions and precedents.

Hence, just as ChatGPT is able to generate codes autonomously, Valle-E is also designed to create discrete audio codecs from listening to an audio sample.

Behaving precisely as a human.

Together with the GPT-3 software for text and Dall-E/Stable Diffusion for images, the Valle-E audio system completes the ChatGPT triptych and aims to revolutionize the field of generative AI.

Speaker Prompt, Ground Truth, Baseline and Vall-E.

The sophistication of the new tool launched by OpenAI and Microsoft lies in Valle-E’s ability to recognize the timbre, inflection, and emotional tone of the person who is speaking and replay it after only three seconds of listening.

The applications in audio editing are many, as are the criticisms of the software’s potential for manipulation and misuse. Not surprisingly, unlike what happened with ChatGPT, Microsoft did not provide the code for Vall-E for others to experiment with.

Samples of speech already synthesized by the software can also be found on the Valle-E site. In particular, several sampling variants can be heard including: Speaker Prompt, Ground Truth, Baseline, and Vall-E

The first option is an audio clip whose speech connotations have to be reproduced by the AI; in the second, a sentence is spoken for which the AI has to propose a comparison. The third, on the other hand, is an example generated with currently available speech synthesis technologies. Finally, Vall-E is the original speech generated by Microsoft’s software.

Potentialities and dangers of OpenAI and Microsoft’s AI.

Microsoft and OpenAI researchers seem aware of the potential harms of this technology. In fact, they communicated in a public paper the following:

“Since Vall-E could synthesize speech that maintains the identity of the speaker, such technology could pose potential risks related to improper use of the model, such as spoofing voice identification or impersonating someone.”

Therefore, Microsoft adds, to mitigate such risks, a detection model can be built to distinguish whether an audio clip has been synthesized by Vall-E. In this regard, the two giants will also implement Microsoft’s artificial intelligence principles during further model development.

However, the risk of emulation is not the only factor generating skepticism and fear. Vall-E was trained using the LibriLight audio library made by Meta, which contains 60 thousand hours of English-language speeches extracted mostly from public domain audiobooks, recorded and read by volunteers.

In any case, to increase its synthesis capacity, Vall-E will need to expand its learning pool to the entire Internet. This next step is what enabled GPT-3, ChatGPT’s predecessor, to achieve impressive sentence processing, writing, and assembly capabilities.

Despite this, the software was also prone to formulating violent, sexist and racist content precisely because it worked on examples taken indiscriminately from the entire Web. This is what could also happen with the new Vall-E.

In this case, filtering operations would require the use of numerous human staff, which, at the moment, the big digital giants do not seem to foresee given the wave of layoffs that is affecting big tech.

Google unveils Bard to compete with OpenAI and Microsoft

As anticipated, competing with Microsoft and OpenAI is Google, which is set to unveil Bard, the chatbot from DeepMind, the company acquired by Google’s Alphabet. Bard looks like an exact copy of ChatGPT, but without the flaw in updates.

Sundar Pichai, Google’s CEO, presented the new software as a tool that draws information from the web to provide fresh, high-quality responses. By “fresh,” he means continuously updated, something Microsoft’s AI still fails to do.

In a nutshell, Bard aims to generate detailed answers to simple questions. Its operation is based on LaMDA, the Language Model for Dialogue Applications, which one of Google’s own engineers had previously described as “sentient.”

There is no denying that Google’s announcement of Bard’s launch was expected by technology enthusiasts. After all, according to reports in the Wall Street Journal, Alphabet, Google’s parent company, has invested more than $31 billion in artificial intelligence in 2021, more than any other competitor.

After the success of ChatGPT, the company therefore decided to summon the very best: founders Larry Page and Sergey Brin. In any case, there is no doubt that artificial intelligence software is an invaluable resource in the field of innovation.

Indeed, even Amazon, Meta, and Apple are certainly not going to sit back and watch what others are doing without taking action. However, while competition is a great accelerator in terms of research, there is a risk that, in the race for the best artificial intelligence, flawed systems with errors, limitations and risks will be used without paying too much attention to the big picture.

Santander mulls stablecoin, crypto offering

Bloomberg reported that Banco Santander is mulling introducing euro and dollar stablecoins, or potentially making a third party coin available to clients, citing sources. This move aligns with broader crypto ambitions, as its digital bank, Openbank, has reportedly applied for a European cryptocurrency license under the Mica Regulations and may enable retail access to digital assets.

Systemically important banks embrace stablecoins?

Major banks are now moving from observers to participants in this expanding market. Should Santander confirm plans to launch a stablecoin, it will be the fourth global systemically important bank (G-SIB) to do so. Societe Generale’s FORGE subsidiary launched the EURCV euro coin in 2023. Deutsche Bank is a partner in ALLUnity, another stablecoin initiative with plans to launch this year, subject to regulatory approval. And Standard Chartered is part of a joint venture in Hong Kong that intends to introduce a stablecoin.

Santander’s involvement could extend beyond an individual initiative. The bank is a shareholder in The Clearing House, where the Wall Street Journal reported that US banks are exploring the potential to create a joint stablecoin. If a US initiative took that route it could involve nine more G-SIBs including Bank of America, Barclays, BMO, BNY Mellon, Citi, HSBC, JP Morgan, TD Bank and Wells Fargo.

Apart from these initiatives, our research shows that more than 20 other banks have been involved in stablecoin projects.

Until recently stablecoins were mainly used to settle cryptocurrency transactions and by residents in countries with volatile domestic currencies. During the last year stablecoin infrastructure has been expanding, especially for mainstream cross border payments. Plus, President Trump issued an executive order prioritizing stablecoins. One of the administration’s motivations is this increases demand for US Treasuries, lowering the interest rate the government pays on the Treasury bills.

Santander as an early digital assets mover

Santander’s stablecoin consideration builds on years of blockchain experience. The bank was an early Ripple investor and previously used Ripple’s permissioned network for payments (not XRP), while also embracing permissionless blockchain activities including issuing a digital bond on Ethereum in 2019. This dual approach led to collaborations with other major players – alongside Societe Generale FORGE and Goldman Sachs, Santander participated in the European Investment Bank’s first digital bond, also on Ethereum. Currently, the bank’s most significant digital money initiative involves Fnality, the wholesale blockchain-based settlement network, where Santander ranks among 20 institutional backers and is part of the early adopter group alongside Lloyds Bank and UBS.
