SpeechFlow

SpeechFlow is a speech to text service sold mainly as an API, built by Bluepulse Inc. It transcribes audio and video files into punctuated, readable text and supports 14 languages, including English, French, German, Japanese, Korean, Mandarin, Portuguese, Russian, Spanish and Vietnamese. Users can upload a file or paste a YouTube link in the web interface to try it, and the transcripts carry time alignment. The product is aimed at developers and businesses that need transcription inside their own workflows, such as conversational intelligence and media processing. The vendor says the API can be deployed in the cloud or on premises, and its comparison pages set it against services such as Deepgram, AssemblyAI, Google speech to text and OpenAI Whisper. Pricing has three tiers. The Free tier includes 10 minutes of online transcription and 0.5 hours of API transcription per month, all 14 languages, time aligned transcripts and one concurrent audio file, with no credit card required. The On Demand tier is pay as you go at $0.0002 per second, with a limit of 10 concurrent audio files and online support. The Enterprise tier is quoted through sales and adds volume pricing, a higher concurrency limit, VPC and on premises deployments and dedicated support.
