The SALA II US English database collected in the United States was recorded within the scope of the SALA II project. It contains the recordings of ca. 2,000 US English speakers (equally balanced between males and females, including some speakers with Hispanic accents) recorded over the United States mobile telephone network.

The following acoustic conditions were selected as representative of a mobile user's environment (some speakers were recorded in several environments):
- Passenger in moving car, railway, bus, etc.
- Public place
- Stationary pedestrian by road side
- Home/office environment
- Passenger in moving car using a hands-free kit

The speech files are stored as sequences of 8-bit, 8kHz Mu-law speech files and are not compressed, according to the specifications of SALA II. Each prompt utterance is stored within a separate file and has an accompanying ASCII SAM label file.

This speech database was validated by SPEX (the Netherlands) to assess its compliance with the SALA II format and content specifications.

Each speaker uttered the following items:
- 6 application words (out of a set of 30)
- 1 sequence of 10 isolated digits
- 4 connected digits (1 sheet number -5+ digits, 1 telephone number -9/11 digits, 1 credit card number -14/16 digits, 1 PIN code -6 digits)
- 3 dates (1 spontaneous date e.g. birthday, 1 word style prompted date, 1 relative and general date expression)
- 1 spotting phrase using an embedded application word
- 2 isolated digits
- 3 spelled words (1 surname, 1 directory assistance city name, 1 real/artificial name for coverage)
- 1 currency money amount
- 1 natural number
- 5 directory assistance names (1 spontaneous, e.g. own surname, 1 city of birth/growing up, 1 most frequent city out of a set of 500, 1 most frequent company/agency out of a set of 500, 1 "forename surname" out of a set of 150 )
- 2 yes/no questions (1 predominantly "yes" question, 1 predominantly "no" question, including fuzzy questions)
- 9 phonetically rich sentences
- 2 time phrases (1 spontaneous time of day, 1 word style time phrase)
- 4 phonetically rich words

A pronunciation lexicon with a phonemic transcription in SAMPA is also included.
