In some examples, one or more local and/or remote participants who are not invited to the conference or who are otherwise not-yet-attending the conference may be added to the conference after the conference begins. For example, a conference participant may ask computerized intelligent assistant 1300 to invite an additional remote participant to join, e.g., to include a colleague who has been mentioned in conversation or who is an expert on a topic being mentioned in conversation. Accordingly, computerized intelligent assistant 1300 may send a notification to the remote participant (e.g., for display at a companion device of the remote participant). The notification may include details of the conference so far as recorded in the transcript. For example, if local participant 164 (Carol) asks computerized intelligent assistant 1300 to invite a colleague who is an expert on a topic being mentioned in conversation, a notification sent to the colleague may include the location of the ongoing conference, along with an indication that the colleague was invited to join the ongoing conference by Carol, along with one or more sentences, phrases, and/or summaries from the transcript in which the colleague was mentioned and/or one or more sentences, phrases, and/or summaries from the transcript in which the topic was mentioned.
