Techniques for streaming real-time automated speech recognition (ASR) are described. A user can stream audio data to a frontend service of the ASR service. The frontend service can establish a bi-directional connection to an audio decoder host to perform ASR on the data stream. The audio decoder host may include a streaming ASR engine which can analyze chunks of the audio data stream using an acoustic model to divide the audio data into words, and a language model to identify sentences made of the words spoken in the audio file. The acoustic model can be trained using short audio sentence data (e.g., on the order of 30 seconds to a few minutes), enabling the transcription service to accurately transcribe short chunks of audio data. The results are then punctuated and normalized. The resulting transcript is then streamed back to the user over the bi-directional connection.

A provider network (and associated methods) permits virtual machine instances to be terminated but imposes some checks to reduce the risk that an instance is unintentionally terminated. In one example, a safety stock threshold is imposed for a group of instances. If terminating instances within that group would cause a violation of the safety stock threshold, the provider network requests confirmation for the instances to be terminated. In another example, a time delay is imposed after receipt of an instance termination request before the instance is actually terminated. During the time delay, the instance is transitioned to an idle state but otherwise persists on its host computer thereby allowing time to revoke the instance termination. In yet another example, the provider network obtains independent confirmation of the identities of all instances to be terminated before such instances can be terminated pursuant to a termination request.
