PowerPoint live captions and subtitles is one of the cloud-enhanced features in Microsoft 365 and is powered by Microsoft Speech Services, according to Microsoft.
Enable live captions for your next sales coaching session
Several spoken languages are supported as voice input to live captions and subtitles in PowerPoint for Microsoft 365, according to Microsoft. The platform addresses the question, "Can I set up captions and subtitles in PowerPoint?", according to Microsoft.
To prepare for your next 1:1, confirm that your specific language is within the supported range for voice input. Since the feature relies on cloud-enhanced services, ensure your internet connection is stable to allow the Microsoft Speech Services to process audio in real-time. If you are using PowerPoint for your coaching slides, verify that the live captioning option is available in your version of Microsoft 365.
For managers running recurring calls, this setup step is the first of six checks. It ensures that the visual text component is active before the audio hardware and language settings are finalized. If your coaching session involves a rep who is deaf or hard of hearing, enabling these captions provides a critical accessibility layer. The captions are generated from the voice input, so the speaker’s clarity directly affects the text output.
When you open your presentation, look for the option to turn on live captions. PowerPoint live captions and subtitles use cloud-enhanced services in Microsoft 365 and are powered by Microsoft Speech Services. If you are using a different presentation tool, you will need to check that specific platform’s documentation for similar features, as the capabilities described here are specific to PowerPoint.
Before the call starts, test the captioning feature in a private session. Speak a few sentences and observe how quickly the text appears on the screen. This allows you to identify any latency issues or language support gaps before your rep joins. If the captions do not appear, check your Microsoft 365 subscription status and your network connection.
This initial check ensures that the visual support system is ready. It is a foundational step for accessibility, allowing all participants to follow the conversation regardless of their hearing ability. By confirming that the captions are active and accurate, you create a more inclusive environment for your sales coaching sessions.

Note that Microsoft also states you can schedule as many live events as you want, but you can only run 15 at a time according to Microsoft. This limit applies specifically to live events in Microsoft Teams. Use this table to verify which settings apply to your specific platform before starting a coaching session.
Configure audio and language settings for accuracy
Audio clarity directly impacts the accuracy of live captions in your coaching sessions. For the best results, Microsoft highly recommends using a headset microphone connected to the device running PowerPoint. This hardware setup is a specific recommendation for that presentation software environment. When you use a headset microphone, you reduce background noise interference, which allows the speech recognition system to process your voice more clearly. If you are using a different platform for your 1:1 calls, such as a dialer or CRM tool, you must still prioritize clear audio input. Close advises that before you make any calls out of Close, you’ll want to make sure to configure your audio settings. This step ensures that your voice is transmitted clearly to the recipient and captured accurately by any recording or captioning tools integrated with the platform.
Language selection is another critical factor in caption accuracy. Not all languages are treated equally in real-time captioning systems. Microsoft notes that the languages marked as Preview are offered in advance of full support. These preview languages generally will have somewhat lower accuracy compared to fully supported languages. However, Microsoft states that our recognition of these languages will improve over time. This means that if you are coaching a team that uses a language currently in preview status, you should expect some errors in the live captions. You might need to verbally clarify key terms or provide written summaries afterward to ensure the rep fully understands the feedback. Do not assume that caption accuracy is uniform across all supported languages. Check the specific status of the language you plan to use in your coaching session.
When configuring your session, consider the following steps to optimize audio and language settings:
- Select the appropriate microphone. If you are presenting in PowerPoint, use a headset microphone connected to the device, as recommended by Microsoft.
- Verify audio settings in your calling tool. If you are using Close, configure your audio settings before making any calls, as advised by Close.
- Check language support status. Review whether your coaching language is fully supported or marked as Preview. If it is a Preview language, be aware that accuracy is generally lower, according to Microsoft.
- Plan for potential errors. If you are using a Preview language, prepare to supplement live captions with written notes or verbal repetition of critical points.

Verify meeting duration and participant limits
Before you schedule a recurring coaching block, confirm the platform limits that govern how long a session can run and how many people can participate. These boundaries determine whether your 1:1 or small group call fits within the tool’s documented specifications.
Webex provides a specific reference for how long a session can remain active. The platform documentation addresses the question, "What is the Maximum Running Time for a Meeting or Event?" according to Webex. Check this page for information about meeting duration before booking a long-form coaching session.
Microsoft Teams has distinct limits for live events and group interactions. According to Microsoft, you can schedule as many live events as you want, but you can only run 15 at a time. If you are planning a large-scale coaching workshop using live events, this 15-event concurrency limit is the hard boundary you must respect.
For smaller, ongoing coaching channels, Microsoft notes that real time updates are only available to 25,000 users at a time and only 25,000 users appear in the channel list according to Microsoft. While most 1:1 coaching calls will not approach this number, it is the documented ceiling for real-time synchronization in the channel list.
If you use group chats to share coaching notes or schedule follow-ups, check how many members you can add at once. According to Microsoft, only 200 members can be added to a group chat at the same time. Add no more than 200 members to your coaching group chat at the same time.
Network configuration can also affect audio quality during these sessions. According to Microsoft, Edge RS2 or later doesn't support sending real-time audio and video traffic through HTTP proxies. If your team uses a managed browser environment with HTTP proxies, verify that this restriction does not block your audio stream before the call starts.
Finally, if you need to reorganize your coaching channels, be aware of the recovery window. According to Microsoft, deleted channels can be restored within 30 days. This window gives you a month to recover a channel if you accidentally delete it during a workspace cleanup.
Check your meeting duration against the Webex documentation and confirm that you add no more than 200 group chat members at the same time before the next session.
