The short answer
A charge from ASSEMBLYAI* SPEECH API corresponds to speech-to-text AI models, speaker diarization, audio intelligence, or transcription API usage from AssemblyAI, Inc.
Why it shows up like this
A line item showing ASSEMBLYAI* SPEECH API on your bank or credit card statement indicates billing from AssemblyAI, Inc. for its developer speech-to-text platform. This charge represents an AssemblyAI Speech Recognition API Subscription or prepaid usage credits used to transcribe audio files or generate automated call summaries. The company provides artificial intelligence models that convert speech into text for software applications.
Billing usually occurs on a usage-based schedule or when an account reaches an automated credit reload threshold. For instance, developers on the platform often maintain a $50.00 auto-recharge balance that triggers whenever prepaid credits dip below a set limit. Common statement descriptors include ASSEMBLYAI* SPEECH API or ASSEMBLYAI INC. If someone on your engineering team connected a company card to an API project, production traffic or batch audio transcription will trigger recurring debits without a manual purchase order.
To inspect the underlying charges, log into your developer account at assemblyai.com/app and head to the Account Billing tab. The dashboard breaks down audio hours processed, active API tokens, and itemized invoices. If you want to stop future billings, turn off auto-reload and delete any active API keys. Keep in mind that AssemblyAI does not issue refunds for processed audio minutes once transcription jobs complete.
