Loudspeaker Box
Echo
The Echo Speech Source Type 4720 is a small active loudspeaker box providing calibrated acoustic signals for speech intelligibility measurements using the Dirac room acoustics software. The Echo Speech Source is typically placed at a human speaker position. The received signal at the listener position is then picked up by a microphone and analyzed in Dirac to arrive at an accurate qualification of the speech intelligibility through parameters such as the Speech Transmission Index (STI). The Echo Speech Source operates from 4 AA batteries or an external mains power supply, and can be mounted on a standard tripod.

AI Virtual Assistant Performance Analyzer
Vocalyzer Test Suite
The vocalyzer test suite has been developed to enable black-box evaluations and benchmarking of AI powered virtual assistants. The goal is to help highlight gaps in performance with measurable, repeatable and shared benchmarks. For the initial task of assessing the hearing capabilities of speech recognizer engines, vocalize.ai has leveraged expertise from the world of audiology; the branch of science that studies hearing, balance and related disorders. Working with talented audiologists, the company has identified procedures and modified them to work with virtual assistants. Audiology tests such as Speech Recognition Threshold (SRT) and Speech In Noise (SIN) are supported by a cloud based utterance database and are readily available for product benchmarking.

Sound Monitoring & Matching API based on Sound Similarity Measurement (for Sound Recognition Projects)
Sound recognition is one of the main application areas of artificial intelligence. Various sound recognition techniques exist and can be used for recognizing speeches, music, environmental sounds, animal sounds, air-borne or structure-borne machine sounds, etc. These techniques contain in common signal pre-processing, feature extraction and feature matching / classification algorithms from a general perspective. However, they differ in implementation in different applications. For example, there are a few good automatic speech recognition software products and APIs, however, they just cannot be used directly in animal sound classifications.
