For short clips it may be possible to place the transcript in the post. For longer recordings, provide a link to a copy of the transcript.

Otter.ai opens a new window
The basic account is free and offers up to 600 free minutes of transcription per month. The transcription also attempts to break down the audio by speaker. Transcribe your audio, host it on your website or web server, and share the link along with the audio recording on your social media account.
Transcribe using Voice Typing in Google Docs opens a new window
For short clips, this is another option for creating a quick transcript.
Open up Google Docs.
Go to Tools>Voice Typing.
Select the appropriate speaker language (e.g., English/US) and the start speaking. (NOTE: You also play the audio from your recording, loud enough for the microphone to pick up the speech and transcribe it.)
