#IBM WATSON SPEECH TO TEXT NARROWBAND UPDATE#

I’ve been using IBM’s Watson’s Speech to Text engine for transcribing call audio, some possible use cases are speech driven IVRs, Voicemail to Email transcription, or making Call Recordings text-searchable. The last time I’d played with Speech Recognition on Voice Platforms was in 2012, and it’s amazing to see how far the technology has evolved with the help of AI. IBM’s offering is a bit more flexible than the Google offering, and allows long transcription (>1 minutes) without uploading the files to external storage. Sadly, Watson doesn’t have Australian language models out of the box (+1 point to Google which does), but you can add Custom Language Models & train it. Input formats support PCM coded data, so you can pipe PCMA/PCMU (Aka G.711 µ-law 7 a-law) audio straight to it. The first thing you’re going to need are credentials. Select “Speech to Text” and you can view / copy your API key from the Credentials header. “transcript”: “hi Nick this is Nick leaving Nick a test voice mail “ Common Transcription Options speaker_labels=true I’ve got an Asterisk instance that manages Voicemail, so let’s fire the messages to Watson and get it to transcribe the deposited messages: curl -X POST -u 'apikey:yourapikey' -header 'Content-Type: audio/wav' -data-binary '' “confidence”: 0.831, Once you’ve grabbed your API key we can start transcribing. Speaker labels enable you to identify each speaker in a multi-party call.

Timestamps timestamp each word based on the start of the audio file, This makes the transcription read more like a script with “Speaker 1: Hello other person” “Speaker 2: Hello there Speaker 1”, makes skimming through much easier. This reads poorly in CURL but when used with speaker_labels allows you to see the time and correlate it with a recording. One useful use case is searching through a call recording transcript, and then jumping to that timestamp in the audio.įor example in a long conference call recording you might be interested in when people talked about “Item X”, you can search the call recording for “Item” “X” and find it’s at 1:23:45 and then jump to that point in the call recording audio file, saving yourself an hour and bit of listening to a conference call recording. Unfortunately Watson, like GCP, only has support for MULAW (μ-law compounding) and not PCMA as used outside the US. Luckily it has wide ranging WAV support, something GCP doesn’t, as well as FLAC, G.729, mpg, mp3, webm and ogg. Watson has support for US and GB variants of speech recognition, wideband, narrowband and adaptive rate bitrates. Voice and mail Watson wasn’t sure of max_alternatives Per word confidence allows you to see a per word confidence breakdown, so you can mark unknown words in the final output with question marks or similar to denote if it’s not confident it has transcribed correctly. This allows you to specify on either a per-word basis or as a whole, the maximum number of alternatives Watson has for the conversation.Thanks for the reply. I half want to look them up and half don't.

A bit like how you don't want to know what they do in a slaughterhouse. I'm with you on everything you said about Cambly. I don't do much outside of the lessons apart from reply to regular students.I need to earn money and have no fucking idea what to do.

Rising Storm is a realistic first person shooter. Rising Storm brings in a whole new arsenal of weapons, that relate to the American and Japanese weaponry used in the Pacific Theater, such as the M1 Garand and the Type 38 rifle.Īll of the core gameplay mechanics from Red Orchestra 2 are present, such as the cover system and bullet drop. Gameplay has been described by Tripwire as asymmetrical, due to the Japanese having inferior weaponry to the Americans to maintain historical accuracy. To balance the teams out, the Japanese are given the Knee Mortar, along with the ability to plant grenades as booby traps, and being able to launch Banzai charges at the Americans, which in turn deals suppression onto the Americans while the Japanese suffer less from suppression themselves. Rising Storm features four playable factions, including the United States Marine Corps, the U.S. Army, the Imperial Japanese Army, and the Special Naval Landing Forces.

The game takes the player around the Pacific with maps varying from the Battle of Peleliu, with a desert-island type environment, to the Battle of Saipan at Charan Kanoa, an urban environment, to the Battle of Iwo Jima and the like. Rising Storm also comes with all multiplayer content from Red Orchestra 2: Heroes of Stalingrad. On September 26, 2013, the Island assault content pack was added, bring with it a multiplayer campaign previously seen in Red Orchestra 2: Heroes of Stalingrad.
