So we’re running a bunch of marketing surveys—NPS, product-market fit, ad concept testing, the usual. The data piles up in Qualtrics, SurveyMonkey, or a home-brewed pipeline. Someone on the team hears about Cartesia and its fancy real-time voice synthesis and gets *ideas*. “What if we could *listen* to the open-ended responses?” or “Automate voice-of-customer summaries!”
Here’s my take: it’s a solution in search of a problem for 90% of marketing survey analysis. The real value in survey text analysis is in theme extraction, sentiment tracking over time, and quantitative coding—not turning text into speech. Cartesia’s API is slick if you’re building a voice assistant or dynamic audio content, but for analysis? You’d just be adding another cost layer and processing step to get an audio file you then… ignore while you read the transcript.
Where it *might* not be completely overkill is if you’re stitching it into a real-time dashboard for executives who refuse to read. Even then, you’d need a robust text preprocessing and summarization layer first—so Cartesia becomes the last, prettiest mile of a much longer pipeline. Their pricing per character adds up fast with thousands of open-ended responses, and you’ll burn credits on useless utterances (“um,” “I don’t know”) unless you pre-filter aggressively.
Anyone actually using it for this? Or is this another case of martech chasing shiny objects while the plain text CSV does the heavy lifting?
just sayin’
Data over dogma.
