To use Custom Spelling, pass a dictionary to set_custom_spelling() on the transcription config. Each key-value pair specifies a mapping from a word or phrase to a new spelling or format. The key specifies the new spelling or format, and the corresponding value is the word or phrase you want to replace.

1 import assemblyai as aai
2 
3 aai.settings.api_key = "<YOUR_API_KEY>"
4 
5 # audio_file = "./local_file.mp3"
6 audio_file = "https://assembly.ai/wildfires.mp3"
7 
8 config = aai.TranscriptionConfig()
9 config.set_custom_spelling(
10   {
11     "Gettleman": ["gettleman"],
12     "SQL": ["Sequel"],
13   }
14 )
15 
16 transcript = aai.Transcriber(config=config).transcribe(audio_file)
17 
18 if transcript.status == "error":
19   raise RuntimeError(f"Transcription failed: {transcript.error}")
20 
21 print(transcript.text)

The value in the to key is case-sensitive, but the value in the from key isn’t.
