Despite the obstacles, L’Équipe and Devoteam were committed to finding a way to create the podcast series while matching the quality of human-delivered content. One key decision was that the AI would not generate any original content. To create the podcast, the team would re-use existing content from the L’Équipe website, created by the journalists. This content was then fed into the gen AI tool using Amazon Bedrock—the easiest way to build and scale generative AI applications with foundation models.
After the initial solution was built, Devoteam created some demo versions of what the podcast could sound like and shared them with the key stakeholders. The team had no room for error, because any mistakes or mispronunciations could raise issues of credibility and trust with listeners. The results satisfied the editorial team, which was impressed with the accuracy of the AI-generated spoken voice. Using the existing content was a significant enabler to building trust in the solution, because L’Équipe’s journalists were reassured that the gen AI tool was not creating brand-new content itself and were satisfied that there would not be mistakes or unverified information entering the scripts through AI hallucinations.
Devoteam quickly built a solution that was able to create these podcasts in a repeatable, scalable way. It needed to be a simple, user-friendly process, because there was limited time to upskill the L’Équipe team to be able to generate the rest of the podcasts themselves. It used Amazon Simple Storage Service (Amazon S3) to store the text summaries generated by Claude 3.5, and then AWS Lambda was automatically triggered whenever a file was added to or modified in Amazon S3. It automated tasks such as validating text summaries and converting text into audio. Finally, it used AWS Step Functions to orchestrate the whole process, step by step, to ensure a smooth and structured production process for the podcast.
After it had a prototype in place, Devoteam could easily show L’Équipe how to repurpose and input the journalists’ content from the website into the tool so that it could spin up a podcast out of it. “The team found it easy to create the podcasts without any previous experience with the tool and have been charmed by its simplicity and efficiency,” says Raphael Dardeau, chief technology officer at L’Équipe.
