Narrative:
On the extended ILS 34R approach into den during an unusual amount of controller changes; accompanied by excessive airspeed changes and awkward clearances; the first officer did not arm the localizer when cleared the approach. I failed; as pilot monitoring and captain; to rectify the situation in a timely manner.I believe; on downwind we were slowed to 210 knots and then accelerated to 220 knots which required a configuration change to comply; followed by a slow to 190 knots. We were then handed off to the next controller who vectored us to intercept the localizer with the clearance to accelerate back to 210 knots to boeng and then 170 knots to corde. It was then; that I realized I had missed that the localizer had not been armed by the pilot flying. I intervened; and armed the localizer prior localizer intercept. We overshot the localizer and the pilot flying opted to go to heading select mode to rejoin. We overshot the localizer by maybe one dot and corrected back. We were then handed off to the next controller; who I queried to clarify our clearance; and who responded that he knew nothing of the airspeed clearances we had received previously. Then; and I'm not sure; but another controller may have broke in. Regardless; we were then instructed to just slow to 170 knots until corde. We continued the approach and landed without further indecent.

Title: A319 crew reported they flew through the localizer on approach to DEN with multiple speed and controller changes.
Narrative: On the extended ILS 34R approach into DEN during an unusual amount of controller changes; accompanied by excessive airspeed changes and awkward clearances; the First Officer did not arm the localizer when cleared the approach. I failed; as pilot monitoring and Captain; to rectify the situation in a timely manner.I believe; on downwind we were slowed to 210 knots and then accelerated to 220 knots which required a configuration change to comply; followed by a slow to 190 knots. We were then handed off to the next controller who vectored us to intercept the localizer with the clearance to accelerate back to 210 knots to BOENG and then 170 knots to CORDE. It was then; that I realized I had missed that the LOC had not been armed by the pilot flying. I intervened; and armed the LOC prior localizer intercept. We overshot the localizer and the pilot flying opted to go to heading select mode to rejoin. We overshot the localizer by maybe one dot and corrected back. We were then handed off to the next controller; who I queried to clarify our clearance; and who responded that he knew nothing of the airspeed clearances we had received previously. Then; and I'm not sure; but another controller may have broke in. Regardless; we were then instructed to just slow to 170 knots until CORDE. We continued the approach and landed without further indecent.
