Status: Resolved We worked with the third-party provider to resolve the integration issue, restoring API availability. Affected components Payments (Operational) Usage (Operational) Text-to-speech API (TTS) (Operational) Expression Measurement API (Operational) Empathic Voice Interface API (EVI) (Operational) Developer Docs (Operational) hume.ai (Operational) app.hume.ai (formerly platform.hume.ai) (Operational)
Status: Investigating Seeing high error rates on TTS and EVI, seemingly due to an upstream inference provider. We are actively investigating. Affected components Text-to-speech API (TTS) (Partial outage) Empathic Voice Interface API (EVI) (Partial outage)
Status: Monitoring Service has fully recovered. The engineering team is continuing to monitor. Affected components Empathic Voice Interface API (EVI) (Operational) Text-to-speech API (TTS) (Operational)
Status: Resolved Issue was resolved Affected components Empathic Voice Interface API (EVI) (Operational) Text-to-speech API (TTS) (Operational)
Status: Identified Certain voices are requiring data to be backfilled, which is causing excessive load on the system. A fix is currently in the works. Affected components Empathic Voice Interface API (EVI) (Degraded performance) app.hume.ai (formerly platform.hume.ai) (Degraded performance) Text-to-speech API (TTS) (Degraded performance)
Status: Monitoring A fix has been deployed. We're monitoring to make sure it's working as intended. Affected components Empathic Voice Interface API (EVI) (Degraded performance) app.hume.ai (formerly platform.hume.ai) (Degraded performance) Text-to-speech API (TTS) (Degraded performance)
Status: Resolved Everything is operating normally again. Monitoring will continue throughout the day. Affected components Empathic Voice Interface API (EVI) (Operational) app.hume.ai (formerly platform.hume.ai) (Operational) Text-to-speech API (TTS) (Operational)
Status: Investigating Multilingual transcription for EVI is currently down. Root cause is being investigated. Affected components Empathic Voice Interface API (EVI) (Degraded performance) app.hume.ai (formerly platform.hume.ai) (Degraded performance)
Status: Resolved Multilingual transcription has been re-enabled. Service fully restored. Affected components app.hume.ai (formerly platform.hume.ai) (Operational) Empathic Voice Interface API (EVI) (Operational)
Status: Investigating Our Speech-To-Speech API is currently experiencing timeouts, resulting in failed calls. Other services appear to be unaffected. Affected components app.hume.ai (formerly platform.hume.ai) (Degraded performance) Empathic Voice Interface API (EVI) (Partial outage)
Status: Resolved An API key had expired and has been rotated. EVI appears functional again. Affected components Empathic Voice Interface API (EVI) (Operational) app.hume.ai (formerly platform.hume.ai) (Operational)
Status: Investigating Due to an upstream inference provider we're seeing some failed requests on EVI and TTS. Affected components Empathic Voice Interface API (EVI) (Partial outage) Text-to-speech API (TTS) (Partial outage)
Status: Resolved Issue was resolved. Affected components Empathic Voice Interface API (EVI) (Operational) Text-to-speech API (TTS) (Operational)
