Spanish Word-for-Word Transcript

I require verbatim transcription of Spanish - language lecture recordings for official documentation. The transcripts must capture every word, filler sound (e.g., "eh," "um"), and pause exactly as spoken.

You will receive source files in MP3 or WAV format and must deliver the final transcripts as editable Word or plain text (UTF-8) files. The sole priority is absolute accuracy; no translation, summarization, or cleanup is needed.

Please confirm your experience with precise, verbatim Spanish transcription.
