Last month, I helped my supervisor prepare materials for an academic seminar. I recorded two‑and‑a-half hours of audio, which transcribed into over 30,000 words. My supervisor said, "Make me a PPT; just distill the core viewpoints."

I stared at those 30,000 words for a long time, thinking only one thing: I cannot even bring myself to read all of this. How am I supposed to distill it?

Later I found that as of 2026, several tools can generate PPTs directly from audio recordings. I tried a few, ran into pitfalls, and worked out some selection tips, which I'd like to share.

Converting a recording to PPT involves far more than format conversion

Many people assume this is straightforward: transcribe audio to text, format the text into slides, and you are done. In practice, the real challenge lies in distillation. In a two‑hour meeting, there may only be five or six valuable conclusions, buried amid countless pleasantries, repetitive discussions, and off‑topic tangents. If a tool simply dumps transcribed text into slide templates, the output will be unusable and you will still have to rewrite and trim everything yourself.

Therefore, when I evaluated tools, I cared less about whether they "could generate PPTs" and more about whether their output was filtered and logically structured.

Practical experience with several tools

Read AI was the first I tested. It handles English meetings quite well, producing logically coherent auto‑summaries with reasonably formatted exported PPTs. However, its transcription accuracy drops noticeably for Chinese content. Especially when multiple people speak over one another, speaker labels are frequently misassigned. It is worth trying if your meetings are mainly in English.

Notta delivers what I consider consistently solid Chinese transcription among these tools. Mandarin‑language recordings seldom require heavy revisions. It can also generate meeting summaries and PPTs, yet its PPT distillation tends to be overly inclusive. It sometimes includes less relevant discussion points, requiring manual deletion.

I discovered Meeting Minutes later. Its PPT‑generation logic differs from the others: instead of chopping up summaries and dropping them into templates, it first extracts core conclusions and action items, then organizes them into slides by logical hierarchy. I tested it on the seminar recording. It produced roughly a dozen slides separating core viewpoints, sub‑arguments and conclusions. Tweaks were still needed, but it saved me the work of sorting everything out from scratch. Its multi‑speaker recognition also works reliably, making it easy to trace who put forward each idea.

DingTalk Flash Notes shines if your team already uses the DingTalk ecosystem. It auto‑generates meeting minutes and PPTs right after meetings with zero extra steps. That said, performance suffers when you feed it local audio files outside the DingTalk environment.

Key factors I consider when choosing a tool

Transcription accuracy is the baseline. If the transcript is riddled with errors, decent PPT output is impossible. I always test transcription quality with a real‑world audio clip before trying its PPT features.

Summary quality determines whether the PPT is usable out‑of‑the‑box. Some tools transcribe accurately but produce rambling summaries with no clear emphasis when turned into slides. This is where tools really differentiate themselves.

PPT editability. Some exports have poor format compatibility; layouts break when opened on another computer. I prioritize tools compatible with Office and WPS for easy editing.

Pricing. To be honest, free tiers suffice for occasional use. For heavy‑use scenarios — for instance, processing multiple meetings every week — monthly subscription costs need to be factored in.

A tentative observation

In my view, no tool can currently produce a "one‑click recording‑to‑PPT" result that requires zero human edits. AI can condense 30,000 words down to 2,000 and structure them into slides, but that final 10 % of polishing and judgment still falls to humans.

Even so, cutting out that manual groundwork saves an enormous amount of time. Previously, building a meeting PPT would take me at least two to three hours. Now I can finish within half an hour.

If you frequently turn meeting content into presentation materials, test tools using your own real‑meeting audio rather than merely reading feature lists. Performance varies widely across accents and contexts. The best tool is the one that fits your actual meeting style.
